What’s commonly overlooked is that the factory wheel sits on a hub that is a couple of inches deep so when you install an aftermarket wheel with an aftermarket hub more often than not it doesn’t stick out any further than stock and if it does it’s minimal. Also, the upper half of a Fiero steering column is one of the most commonly used steering columns in the world (it’s used in a majority of GM’s from the 60’s through the late 80’s, lots of Jeeps, AMC’s and aftermarket products). Because of that it’s one of the easiest to find adaptor hubs for. Also, The Fiero wheel is bolted to its hub with a six bolt pattern that is also same pattern on a lot of aftermarket wheels so you can attach an aftermarket wheel (if you get the right one) to a Fiero hub. With that said, it’s actually easier to drive when the wheel is closer to you (look at race cars).

My APC wheel came with a 3" long adapter section, but I was able to take it apart, keep the splined hub and then make a 1/4" steel pattern adapter. I need to take this one off and get some better pics.
I just spent the past half hour searching, but could not find it? I did do a thread where I used the stock GT hub, and measured, measured, measured, then redrilled to fit my Grant wheel. Long arms, and there was no way that I could live with the adapter. Good luck with the mod.

Don’t take this the wrong way, but I think you’re making way too much out of this. I put a Sparco hub (from Speedware Motorsports) on my 87GT and at 2” it’s 1/2” taller than the factor hub (you would be hard pressed to notice a difference while driving). However, if you insist, NRG sells a couple of quick release hubs that are designed to be short.
At Speedware, go to "Tuning and Track Equipment" and then "Steering Gear".

1/2" would be fine, but I'm pretty sure my adapter adds at least 1", maybe more. Don't get me wrong, I've gotten used to it, but if I had a choice I would love to have the steering wheel a bit further away from me. (My arms are long and get tired on long drives) I have the seat all the way back, but that makes it harder to press the throttle, or clutch all the way to the floor. (without slouching)

I used the billet Grant adapter for my Momo wheel. I just redrilled and counter-sunk some new holes in the wheel. My Momo has a leather center to cover all the screw holes... I was going to use the NGR but couldn't justify spending that much when the Grant was 1/3 the price... My wheel is very close to the stock position...
Also, keep in mind, some steering wheels may have a different offset to them; which may position the wheel closer to ya...
Kinda hard to see in this pic, but you get the idea

I have done these. Grant sells a 1" adapter that puts the steering wheel about the same position as stock (first two pics below). Then as mentioned you can modify the Fiero hub and install the wheel to it (last three pics below).

Maybe because it's late, but I'm not quite sure I understand correctly what you mean by "modify the Fiero hub". The pictures didn't clear it up for me.
I remember reading about using some part from a 3-spoke OEM Fiero GT wheel, but I'm nut sure what was meant.

Sorry. I don't have more pictures because a good friend did it for me to help me have car ready for RFTH. The stock wheel is riveted to the rear ring (hub) part. You take those rivets off and discard the Fiero wheel. Then you adapt your new wheel (drill, align holes, rivert etc.) to the stock ring.
Part number shown on the box is also the correct part for Fiero. This short adapter will put a MOMO or Grant wheel, (depending on amount of dish), in the same appox. location as the stock steering wheel. VERY nicely made adapter, but also pricey. (You get what you pay for....) ------------------

I really couldn't say. There are no dimensions given in the link you provided. The NRG adapter is approx. 1.375 - 1.500 thick and it's machined out of a soild piece of high quality aluminum. It is nearly identical in thickness to the OEM part that is on the back of the Fiero steering wheel.
I've looked at the Grant adapters and have even used a few of them in the past and what I recall is that the main mounting piece is a zinc diecast part with a stamped metal, painted shell that covers it. They all looked the same if not very very similar to the parts in the picture in the link you gave. Personally, I would NOT trust that diecast part, but maybe thats just me. I also don't like the steering wheel to be attached to the adapter with just 3 screws,
(and, YES, I know the shear strength and pull-out strength of the screws and I have a pretty good idea of the yield strength of the adapter material, so we can just chalk this up to personal preference as well.....)

Well I do understand that part of the reason the bronze colored part that attaches the steering wheel to the adapter is so flimsy so it gives way in case of an accident. Kind of like the steering column is designed to collapse on impact. Maybe that's the reason the hub is made to break as well? :shrug:

Alex4mula, thanks for explaining it with the links. I think I finally understand it. (sorry, I guess I'm a bit dense. )
The version I have right now is what came with the steering wheel, which is the accordion looking long piece. Getting rid of that extra length will make me so happy and will make for a more comfortable driving position.
Note: I put 1000 miles on the Fiero a week over the past few weeks, so the close steering wheel can be quite tiring.

Yes. Discard that one and get any 1" version.

Sorry I didn't see this thread earlier, but in case anyone finds it in the future - there are some instructions out there (courtesy of Mr. Mike) on how to modify things so some aftermarket wheels can go on without any lengthening adapters -
You can buy an aftermarket leather wrapped steering wheel from an auto parts store and adapt it to the original hub. Doing this adaptation will keep the new wheel in the same position as the original (I hate those goofy adapter kits that push the wheel 4 inches towards you). The hub is a round hockey puck shaped steel part that fits on to the steering column. The steering wheel rim and spokes bolts (machine screws) to this hub. A. Remove the horn button / remove the retainer clip / remove the large nut holding on the hub / remove the wheel. B. Drill out the rivets holding the horn button ring & rear plastic collar, remove the screws holding the wheel to the hub. C. Screw the new wheel to the hub, (you may need to drill holes in the new wheel to match with the hub). Use Lock-Tite. D. Rivet on the rear collar and horn button ring, replace the large nut and retainer clip. Be sure to buy a new steering wheel that has a similar diameter and NO "dish" (the distance between the hub and the rim when placed flat on a table). The original Fiero steering wheel is flat and has no "dish".
