I recently bought a 74 XJ6 that came with a set of pristine seats from a later model year (mid 80s, I believe). Because the original hides are in sorry condition I'd like to swap the new for the old seats, but understand that modifications will need to be made.

If anyone can provide (or direct me to) instructions on what mods need to be made, etc., I would very much appreciate it.

Thanks in advance!
