If you can't fix it with a hammer, you've got an electrical problem

since i seem to be getting so many PM's about my hitch, ill answer right here
the trailor hitch/bike rack hitch jack, lifting and resting points...

The control arm bolts are M12 X 1.75 X 90 metric grade 10.9.

The three spring hat mount nuts are M8 X 1.25 (they are called prevailing torque lock nuts - all metal with a deformed top which acts as the locking mechanism)

Lower ball joint pinch bolt nut is M10 X 1.5 grade 9.8

I know I have the strut to knuckle bolt dimensions somewhere if you need them.

Those would help as well. Might as well add a couple more nuts to the list of new hardware. What about the two on each strut shaft? Might as well get new ones of those as well.

The strut to knuckle bolts are M16 X 2 X 80 (10.9), although you may want to double check the length since I measured the ones off my '88 which may be a little longer to account for the rear sway bar bracket. To measure the correct length use a metric ruler under the head of your old ones and measure in mm's.

The central strut nut on the strut shaft will depend on the make of the strut so I can't help you there.

awesome, many thanks.

where do you get this info?? i dont recall the FSM having this sort of info in it.

I get most of it from the Fiero illustrated parts manual (also called the P22 or the P-Book). I got a hard copy many years ago when the dealerships were switching over to computerized versions of the same... they were throwing them out! Most of the bolts are in there, but occasionally you'll come across some like the strut to knuckle bolts or the bolts that hold the transmission to the engine that were forgotten, or the book simply lists that it's a "bolt" without any of the specs

Here and there in the FSM there are lists too. For example page 6A2-24 of the '86 manual lists most of the engine bolts along with the torque to be used.

Oh wow I never knew the p22 had this info in it!
