I have an 86 fiero and I’m looking to changing my stock bolt pattern to 5x120. I did a search and I see people have change bearing but they didn’t post from what donor.
I know 88s can be redrill.
So what’s is the best way without breaking the bank to making front and rear 5x120 also I’m looking to upgrade brakes to 13” rotors. I was looking at the c5 rotors

People used to swap corvair (and nova/chevy II) front hubs with the 5 x 4 3/4. https://www.fiero.nl/forum/Forum2/HTML/132832.html

For the rear they swapped the HD pontiac 6000 or dustbuster minivan uprights and modified them to accept the S10 4x4 front wheel bearing.

Neither is a bolt-on solution.

Neither is a bolt-on solution.

For the rear, the A-body or U-body uprights can be drilled and spot-faced to accept C7 Corvette rear bearings using 33 spline outer CV joints commonly used on Dustbuster minivans and other large GM cars.
Not a bolt-in in that the uprights have to be modified, but that can be done on a bench and then everything else bolts together.

The latest Dustbuster uprights accept the same 11x1.25" rotors and calipers as the LT1 fourth generation F-bodies.

Will, when are you going to finish your CAD design of the 88 rear uprights?

Can I get my car rolling again first?
