i'm running the front and rear suspension from a '73 under mine.
i was going to type 'under my '66', but i'm in the process of merging the best parts of a '64 gmc shortbed and a '66 chevy big window fleet.
running the '73 rear on the '66 required drilling holes for new spring hangers, not required on the '64 since it was already set-up for leaf.
the front is a bolt in swap for both my '64 and my '66o ther than drilling some holes for sway bar mounts. i also moved over the power steering so i purchased the rez(?) conversion kit.
one other thing, i had to go to five lug rims.
