I've got a pair of '74 seats that came with my project '72 Grabber. Ive got new correct '72 seat skins and foams on the way, but upon disassembling these '74 seats I discovered they use an integrated seat back foam/spring assembly that sorta locks into place on the back frame. This is completely different than the 72 and earlier designs. (See pics) does anyone know if '73 was the same as '72, or was it the '74 style?
