Troy,
You are correct... My mistake as I misread Kramer's Catalog. I just spoke to Cindy at Kramers. While the seat brackets look exactly the same, the 1965 seat brackets are two ( 2 ) different heights due to the 1965 floor designs while the 1968 seat brackets are all the same height since the 1968 cars have a flat floor design. Please disregard my previous post as I just deleted it.
Sorry
