I did a new engine harness as well was and headlight relay as well. Question what tires size and wheels are those offset? Can't recall did you swap rear and spring location rear?
Fronts are 18x9 +35 with 275/35/18’s. Rears are 18x10 +38 with 295/40/18’s. The rear axle is a ‘68-70 B-body 8 3/4, it also has a 1/2” spring offset. DoctorDiff 13” cobra style front disks and 11.7” rear disk. Front fender lips have been rolled, rear has had a “reverse tub” and the quarter lips have been rolled and pushed out. Details on the reverse tub are a few pages back.
