Sorry if I am posting incorrectly. My hubby is a rookie at posting on forums and I a rookie at cars but I bragged I could find an answer for him.
He owns a 1965 Dodge Coronet and wants to install seats he purchased out of a 1967 Plymouth gtx. The seats came in 4 pieces. No bolts or brackets, etc. Need some sort of diagram or instructions. Thanks for any help.

 

welcome and can you ask the people from which you got the seats from as where the brackes are off them

 

I have somewhat of a "parts book" file that may not be complete, and looked in a couple of my shop manuals. Neither is much help. The shop manual shows some of "seat buildup", IE dealing with upholstry skins, but that's about it.

 

I hope he didn't pay a lot for those seats They should have come with the brackets unless he was told otherwise. Most wrecking yards do not like to split them up..
Any brackets from a B body should fit E body probably A body up to 70 probably.
The outer holes in the floor pan will work May or may not need to drill the middle holes for the seat brackets, the pan metal reinforcement should be there.. If you can't find anything I can get some pictures but not for a few days I have some seats in storage..
