Recently I recently ran into a problem with my 1987 Pontiac Fiero SE. It has a 5 speed isuzu transmission, and the plastic insert on the clutch arm broke. There is no good way for me to recreate this plastic piece and maintain the strength that it once had. The link lower in the post is for the diagram that I found to be most accurate to the assembly, and the part that I am referring to is first on the list (001 LEVER, CLU FORK (1986-87 MG2) (CA, US)) I have searched through other threads and have had no luck. So far I have found that this part was once reproduced although I am not sure if it is available for purchase any longer. If anyone has a good idea of where I may be able to find a working clutch arm, or the cast steel version any help would be incredibly appreciated.

Hi! Welcome to Pennock's! I see this is your first post. I too have a 1987 Fiero SE. You mention an Isuzu, so I assume it's a 4 cyl? I'm just curious, do you have any pictures? The 87 SEs with 4 cyls are super rare... doesn't really make them any more valuable, but they were rare never the less. It was a model that basically came with all the V6 stuff... trumpeted exhaust pipes, aero package, the extra gauge pod that sits on top of the HVAC vents in the center console, etc.
Just wanted to be clear this is what you had. If you have a V6, then your transmission would be the 5-Speed Getrag.
Hi I think i would take the arm and slave cyl to a local machine shop and have them turn some industrial bushing plastic on the lathe . if too expensive maybe someone on the forum might have one that is still useable. But remember a used one will be 36 years old and may fail like the one you have. sleek

Yes it is a 4 cylinder. I have a had a hard time finding any information on my exact Fiero so the fact that they are uncommon would make a lot of sense. I attached some pictures of the plastic piece that broke, as well as where it was located on the arm. I also attached a picture of the entire engine bay for reference.

I will look into getting the piece machined. In my research I found that at one point a completely steel part was produced instead of steel and plastic. Because this part is no longer made ideally I would like to find someone who bought the steel part while they were still being produced and are willing to sell. You do bring up a good point about used parts being just as reliable as the one that broke, but in the meantime my fiero is not driveable so anything will do.
Considering all the various transmissions (Isuzu, Muncie, Getrag, 4-spd, 5-spd) that have come in Fieros from the factory, I'd be pretty surprised if there wasn't a lever from another application that would work.
I have an Isuzu 5-spd swapped into my '84 (with a duke), and it seems from what I remember that the lever is a solid metal unit. I'd have to take a look to verify that. [EDIT] Well, so much for my memory. (I was probably thinking of the Getrag in my '88.) I had a look at my '84 and it's the same clutch lever as pictured above.

good pics. Yes my 85 with 4 speed has very similar arm if not exactly same. If you cannot find a used fiero one you might get one from a caviler or citation or sunbird. these transmissions were used in multiple GM econoboxes. the piece that is broken loose is for the slave pushrod ball end to ride in and allow the arm to pivot to keep alignment. Probably one could be made out of metal without too much effort. It looks to me that the lock tabs have broken off the pushrod side of it but the rest is still in tact to use as a pattern.

I have a customized 86 Fiero/Ferrari F40 that came with a V6 and a 5 speed Isuzu transmission. And if I remember correctly, it has a plastic insert in the clutch arm for the pushrod from the slave. I guess I should take another look at that, and see if it is showing any signs of deterioration. I know when I redid the clutch disc and resurfaced the flywheel, I had to work with what was in the car, because other parts did not mate up.
