I have an 83 mustang and put a 87 thunderbird rear end with disc brakes. now i have tire clearance issues. i had 275 40 17s with my 7.5 rear end and had no issues. im using the same tires and rims. are there any shops that do a mini tub in the upstate NY area? or should i have the rear end shortened and axles respline? i have a Detroit locker and 31 spline moser axles.
