One more try...
Well I'm back to looking at trying to fit the YO 17x8 wheels on the front of the project car.
was talking to a friend and he suggested C-Body rotors. He measured one he had and said they give about .270" more BS plus the rotors are thicker, also a plus.
Took my 2 front wheels into a machine shop to have the back of the wheel mounting surfaces shaved.
The backs have a lot of material to work with. They have about 4mm that can be removed before getting flush with the backs of the bolt holes... Not sure why they are like that. There's a recess space on the back side behind each bolt hole. We are removing the 4mm of "Extra" material + another ~3.5mm, 7.5mm total.
I ordered (1) 73 C-Body Rotor off Amazon Prime, (Free Returns). Bendix PRT1072 Chrysler PN 3683969, crosschecked on Rock Auto. Hopefully that is the right rotor to match up with my 73 up spindles/bearings.
Combined, I calculate close to 4-13/16" final BS. Not quite the 5" target but will see how close that gets us.
Trimming the lower front corner of the fender is not off the table but it's an expense I'd like to avoid for now, if not all together.
