Hi, I'm still stymied by the nonexistent Clutch slave cylinder bracket and the throw out arm. This is for an 1984 Muncie 4 speed with a four cylinder engine.
What are the alternatives to these parts or am I going to have to start the engine with the clutch engaged and the transmission in gear. How long until the starter or its mount breaks?
Is there a hydraulic throw out bearing that could be used? That would eliminate the search for hardware that is nonexistent.
Were there other cars that used this bracket and throw out arm? I know that is a tough question.
I could swap the transmission to something that the parts are available for. That would be lots of work and some considerable amount of money. For me, any amount of money is considerable. PullRParts transmissions are reasonably priced but the work space is very lacking! Dropping a cradle in a sand lot isn't my idea of fun let alone even an accomplishment.
I'm stuck with an unusable car until I get some solution to this issue.
Thanks for all your input,
Lyle

If you're low on money/resources, talking about swapping transmissions and retroffiting an HTOB are the most bass ackwards ways to go about getting your Fiero fully functional.
You do modifications like that when you do a bling-bling megabuck build and are planning a lot of downtime for the car.
Seriously, just find stock (or equivalent) parts. They built 136k 84 Fieros, so there are a bunch out there. Also there is some interchangeability with the 85-86 4-speed transmissions.
Just find a u-pull-it junkyard with a 84 Fiero (85-86 is worth looking at too), and take what you need.
You can even drive your Fiero to the junkyard. It's not unuseable... it's just a bit less luxurious. From my (at the time) home in Valcartier, QC, I drove my Fiero with no real clutch release functionality to: 1. Saguenay, QC 2. Montréal, QC 3. Plattsburgh, NY - I crossed the international border. In this instance my clutch master was sitting on a shelf at home, absent from the car. You can check how far I went using google maps.
If you have to drive 6 hours to find the right u-pull, well, maybe that's what needs to be done if you want to keep this car.
Staying stock is pretty much always going to be the most economical and expedient manner of getting your car fully roadworthy again.
Post in the Mall section asking for Cast Iron clutch arm and slave cylinder bracket for Muncie 4-speed. Someone may have a parts car with what you need.
I don't recall the 84 slave bracket looking like that. I know the one you show is for the 4-speed V6 applications.
That is very likely correct. I needed some sort of image to show what I was looking for. The '84 used a Muncie four speed. Later years used Isuzu or Getrag even behind the four cylinder.

Good point. Here's the slave mounted on an '84.

No, the Getrag 5-spd was only ever used with the late '86-'88 V6. (From '85 to early '86, a 4-spd Muncie was used with the V6.) All '85-'88 L4 Fieros used a 5-spd Isuzu.

It may still be possible to bolt the V6 stuff onto the 84 case, but I am not sure.
About 3 years ago when I was building a FrankenMuncie, I don't remember there being major differences between the cases (other than the obvious ribbing). However, my memory of that is fading away.
I didn't keep a smooth case in my (too large) parts stockpile.

Does anyone have a picture of the 1984 clutch slave bracket?
The original '84 slave bracket is in that picture I posted above.
However, I believe it was a rather poor design, prone to cracking. As has already been mentioned, you might be better off going to a later style slave and bracket.
The slave cylinder in the posting above is not like the slaves that came with the car. What I have is the flange mounted cylinder. I don't have a cylinder with the mounts on the side. Just to add to the confusion. The auto parts stores show the side mounted cylinder for a 1984 with the 4 cylinder engine.
I can't even begin to guess what the cylinders that came with the car belongs to. There is a NIB cylinder and a very used cylinder.
Well... that stands to reason, as the side mounted slave was what originally came on the 84's.
Using that cylinder would make the mount simpler but finding one is not so easy.
I have to wonder why there are two flange mounted cylinders with the car. One is new, one is used.
It appears from the collection of parts with the car that someone was trying to get it running. Then they found out the engine is locked up. Someone had even taken the bolts out of the cradle.
The more I dig into this clutch situation the more confused I get.
I think I will wrap a string around the release shaft and run it to the driver's seat. Pull hard to release the clutch.
At this point I really don't care what the car had when it came from the factory. It is a work in (no) progress.
A link to Rodney disclosed that he also was looking for help with a slave bracket.
The area where the slave cylinder would mount has no bolts or bolt holes other than the transmission to engine bolts.
The responses to my quest for information indicate that there is no one solution to this problem. The almost correct answer depends greatly on the phase of the moon.
I will continue me quest for the Holy Grail. It is out there somewhere.
I was at a wrecker today. Got the bracket and slave off a 1984 4-speed. I grabbed the slave too because it looks fairly new - unlikely the original. Didn't leak, fluid was clean and hydraulic line came out easily.
Didn't realize you needed the arm as well (it's the layered steel piece - not cast). Could go back and get that too...

Hi fierosound, That is awesome. I will have to check my car to see if that is a fit. I did look yesterday and didn't see any bolts not used or bolt holes that were vacant. I will look again. The pictures are very helpful. Don't make a special trip for this. If I know the parts are available I can proceed with work on the car. Thank you,
Lyle

The clutch slave bracket only makes sense when you see engine and transmission bolted together.
The slave bracket has one bolt going to a corner of the head of the 4-cylinder above top left transmission bolt. The other bolts to the transmission itself into a "speed nut" kind of thing.
You show it in one of your pics below the slots for the transmission cables.
I took this picture and also got the clutch arm that was there.
On the V6 - I'm sure this is where one end of the slave bracket would bolt to above the same top left transmission bolt.
