Yes...decided on Dr. Diff front and rear disc kits, w/ lg bolt pattern, 12" front, 11" rear. going a bit over board with the suspension, brake and steering upgrade, but she's going to handle, steer, and stop like a new car.
My dilemma now are wheels...like to go with 17" x 8" year one rally's (think they would look great), but they are made for E-Bodies, the backspace offered may not be enough to clear the wheel well openings, at least with taller tires sizes...don't like the low profile look. Only other rims I've seen on our cuda's that look good, (to me), are the Torq Thrust 2's (the affordable ones are Made in China, Boooo!), think I could go up to 4-3/4" back space with them, and taller tires. I wont know exactly how much back space i need until everything is assembled.
I will post my results on the wheel back space required with these kits and our '67-'69 cuda style. I searched the posts about what other FABO's members have on there cars, but didn't find much/anything on what backspace was used when converting to Dr. Disc 4 wheel kits and 17" wheels. might not be a heck of a lot of people that have done it. Most people I believe, have, Formula S's and want to restore them to stock. Mine started out as a 318 car, so upgrading is a no harm no foul thing...if it was a "S" I would think twice.
