Ok so this is the second Fiero that i got that has a broken gas pedal! As you know everything made of plastic on these cars break. They split right at the the connecting point. I thought about fabricating one out of aluminum or steel that won't break but i really don't want to go through extremes to fix it. Does anyone know where to get a new pedal? I tried the fiero store with no luck. Are there any aftermarket ones made of metal out there? My friend with a Fiero also has the same problem. we went to a wrecking yard this week to get one out of the only car in vegas and the damn pedal was broke in that one to.
Pedal part is common to many GM cars, even trucks. For new, Try http://www.dormanproducts.com/ then order thru many parts store.

Actually it is Alto Ave. And not just weekdays just about everyday some one is there. Once it gets hot out we get there later and later. We were the largest Fiero yard in the world at one point but we have been down sizing lately.
It should be pretty easy to fabricate a metal one. Id have to look at one to see whats needed. Off the top of my head without any idea how one looks, a piece of heavy aluminum plate and a hinge should be almost there. I had one car, dont even remember what it was that didnt have a pedal at all. It had like 3/8" metal bar bent to shape and pivoted in a bracket. The part that your foot rested on was just a roller about an inch in diameter and a few inches wide, and it was mounted to the end of that bar. Throttle cable/linkage was on the other end of it. Might have been my Mercedes SL.
Look online at places like Summit or Jegs, or even a race car specialty shop.

Im really thinking about doing a nice hand fabricated billet aluminum one . I can copy the design of the original part but give it a nice billet race look. Maybe even have it router cut by machine. I may even have them cut out parts to do maybe 10 pedals or so since i have 2 fieros and some friends that may want them as well.

You can always make one that looks like a foot, toes and all, they sell those online for those ricer guys but I am sure they will work on a Fiero. I can cut one in any shape you want with my plasma cutter, out of any type of electrically conductible metal. hell I wouldn't even charge you but for material and postage. it wouldn't take me 2 mins to cut it.
but back to the plastic ones braking, I have only ever had one brake, gas pedal, you do know the entire Fiero body is plastic and those last decades. plastic, depending on the type can be almost as strong as steel, think about the tiles on the space shuttle. you may have had someone get a water bottle stuck under the pedal and just kept pushing until they broke it, you know those steel water bottles. but as a rule they last almost forever unless broken by someone out of shear brute force. and yes who ever said they are all just about the same through the entire GM line was right, when you go to the bone yard ask them what will work, they have a substitution book, well list on their computers now that will give you every pedal that will fit the Fiero without any modification.
Actually I have a spare one in my parts car 84 out back if you just want a factory one. but for that you will have to wait for the snow to melt, there is still 2' of snow out there surrounding that car.
Not to mention, Auto zone sells them. And I'm sure every other parts store sells universal replacements,.
Out of the over 160 Fieros we have gone through and the over 150 members we have/had in town I have yet to ever see a broken gas pedal. How are you breaking gas pedals?

OE pedals can break over time just from spring load. If you look, many are close to breaking. watch the pin and clip on left side of pedal. Now squish spring to pedal front. See them move? The whole clip should be on pedal but plastic hole now oval shaped from spring load because Left side of Spring pushes on plastic next to hole in plastic. (Right side moves too but much less obvious most times.) This example one I have only a little plastic left before it breaks. (Thanks Macarchie for this example. Donations of old, even "dead," parts are handy.) (I did some scratches to remove the clip.)
A view from the back.
Can you fix old pedals? Maybe but you're taking chances that many don't need the headaches later if your DIY fix causes a wreck.
I did look at Dorman... nothing. I did find 20760 but said won't work. Did quick search # on back... 10023366... nothing.

yup... Most aftermarket ones are like that.

This is why you never use wet lube on parts exposed to dirt. (I found this later and I thought people should know.)
Dirt will accelerate grinding the hole in plastic and the hard spring cut into the steel pin. To make the problem worse, someone used wet lube that traps even more dirt.

Why cant you epoxy and rivet a metal plate on the plastic pedal at both sides ? Then drill them for the shaft to go thru...even larger and put a brass door pin bushing in them...?

Glue/epoxy won't stick to polypropylene. (The PP below the part number in images above. GM is good as labeling plastic parts as to what kind of plastic.) Hinge bushings are likely too big.
Polypropylene is easy to weld but doing this on the gas pedal is a lot harder than many Internet directions would say because the spring puts a lot of load on the weld itself. This means any defect and the weld would break likely soon.
Given time and many more miles and i think many of you will end up with a broken pedal. Nothing last forever and there is a lot of stress on that little pedel. Im not really into the whole little foot thing I'm looking for more of a standard shaped pedal with a billet look. Thanks for all the advice.
I recently found a 2nd broken pedal on my 88 GT that was broken from prior owner. If I recall, got the replacement from fierostore. But they don't carry them anymore? I looked at the replacement I had installed, and it cracked where the metal foot slips through. I am not rough on my car either. Just a very soft plastic. :/
Hell, I took a torch and bent my pedal and I still don't have problems, that was like 8 years ago. (To fit a chrome one) He has access to more pedals then he could ever use right here in town. no need for after market.

Maybe... Mine is worn but not as bad as example images above. Car has ~220,000 miles.
Update: I restored the pic's for above lost by old PFF Image server & add this for the Bearing Block holding the pedal. Why? If you have the problem above then very likely the Block has problems too.
⚠️ Warning: The Block like brake/clutch pedal bushings have No Lube. If you lube the parts, use Dry Teflon on the Metal then allow the lube to Dry. If already has wet lube then plan to get another set.
First is how the block as installed. When you push the pedal the rod/arm pulls the cable to floor too. Note: Most pedal assemblies have 1 or 2 clip nuts to keep the part together @ the factory. If there missing very likely the part was taken apart before. The Roll Pin just keeps the Rod centered.
This is the Rod & plastic w/ cover off showing some wear on the rod. Notice only parts of the plastic contacts with the rod.
Larger Problem is the load tries to twist the rod so on pedal side rod wears the plastic but other side rod wears the metal cover.
To check the plastic for wear issues...
How to fix the plastic? Not sure. The plastic is likely Not Polypropylene so can't just "weld" new PP in the worn spot. (For people that work on plastic a lot, just doesn't feel or look like most PP or ABS parts.) For a temp fix, In my case Most of the wear was on the plastic curve so I put a piece of Nylon Zip Tie in between plastic & rod on the pedal side until I got a better used pedal assembly. Tension just holds the strip in there.
Markings? Only ones seen are... Besides the Part # I have no clue what others mean. GM Plastic Types I've seen don't use Periods & never seen P.O.M. as a GM division or contractor. All you get searching plastic types are the fake "recycle" marks so even if "square W" is the plastic good luck finding that now.
