Re: 1970 f250 compatible with 1976 for a/c unit?
By the time you're done replacing, dehydrating, and restoring the AC, you probably could've bought it from LMC. A lot of things such as seats, engine mounts, etc. are interchangeable from 57 to 96, mainly the outer skin and cosmetics changed. Technically, you can take your shell and drop it on a 92 with only a few modifications. Unfortunatley, I don't think the glass is interchangeable.
