I've put some metal spacers between the seat and floorpan in an Olds Delta 88 to raise the seat one inch. Has anyone ever tried this in a Z before? I've always wanted to, but haven't tried and don't know if it can be done. It sounds easy enough...remove seat...put in some sort of spacer and longer bolt...and mount seat back in to proper place. Anyone got ideas on this, 'cause I've never had the Z's seats out?
