Wipe out,
I feel your frustration because I went through the same thing. But I am telling you that the set up that I have in my thread above is the exact set up that Ed Parks uses. I even tried having a custom axle made by a local driveline shop and it was wrong before I came to the knoledge above in my thread.
****** you must use an OEM Fiero outer cv joint from a Manual Fiero tranny*****
this is indeed where I also ran into a problem----some aftermarket companies have begun using the smaller internals and shaft diameter to replace the manual Fiero CV joints.
Here in this thread you will see what I went through finding out that aftermarket axle builders were using smaller shafts-
https://www.fiero.nl/forum/Archives/Archive-000001/HTML/20050410-2-056573.htmlUse the minivan axle and and OEM manual Fiero cv joint and it will indeed work. Read the obove thread carefully from beginning to end and watch as I bought and tried axle after axle------the splined hole in the fiero cv you need will have a measurement of 1.035in if I remember correctly. If yours measures .083in it is either an auto fiero cv or an aftermarket manual neither of which will work. Take your calipers to the auto parts store if you have to-----might be easier to ask in the mall here for a manual fiero cv joint with 1.035in inner diameter. I'm sure someone has one they can ship you.
I know you are frustrated because I was pulling my hair out----
I hope this information helps you.
