It is indeed an 86 up issue . I know 85's weres not part of this problem. the only thing you will encounter is dipstick issues. It's harder to cure the dipstick issue if you are going the way i am because of the stupid upswept exhaust manifolds they started using in 82.
I think the 86 up flywheel bolts MAY?? be a diferent size too. crossy
