I am stripping a 78 Buick Century.I was wondering if the disk brakes would fit a 66 Chevelle or even a 70 Chevelle.I was told it might work.So I was wondering if thier is a sight where you can see what crosses over or if any of you guys know for sure..Thanks

If I'm not mistaken, a 78 Century is a G-body, like a Regal, Monte Carlo, Cutlass, etc...

Those brakes will work on a chevelle, but they have way too small of rotors (10" ???)to really be a good effective swap for adequate braking in a chevelle. While they're certainly an improvement over drums, IMHO they're not worth the time, money, and effort to rebuild them to use on a Chevelle.

Spend a little more for 11" chevelle brakes, or 12" B-body brakes.

man do not use g-body spindles on ur 66. i have a 66 chevelle that i attemted to use 79 el camino discs on and i changed ball joints, put the spindles on and hooked up the new tie rods and it was there right? NO, on the pass side the inner tie rod hits the centerlink if you push the car down a little !!!! at ride height it was ok, but like if u hit a bump in the road or anything that would cycle the suspension a little, you would end up breaking that and that would not be good. i played with this for a while and all i could do is heat up the tie rods on the pass side and bend them to make them work. i decided not to use this set up.
