My 85 k5 column is not worth rebuilding since it was rebuilt twice by mickey mouse. I was wondering if a 89-91 k1500 will fit my blazer. Has anyone tried this? What modification is needed? Are the steering column lengths the same? Is there other GM vehicles that can be interchanged with a 85 chevy K5 besides a GMC K5? Also my local checkers, NAPA, and carquest do not have a listing for an 1985 K5 driver side engine mounts, how peculiar.
