I had them on my 70 GMC C2500. They have two holes, one for about an inch drop and one at an inch and a half. I used the one inch. On the 1 1/2" you may need to trim the rear bed crossmember for clearance.

I did a flip on my 69 short step and it netted 7 1/4" drop. I had purchased the shackles also for it if I wanted it lower, but no way I could run them without c-notching and I would rather not.
