My 1970 40 currently has some seriously ugly seats for a Mazda MPV van. I've been looking to install something a little nicer and have read all the threads on seat swaps that I could locate. But what about using bucket seats from a later model cruiser? There aren't that many Cruisers in this area, so I can't just go and check the different ways they were mounted. My '70 has the tool box bin under the drivers seat and gas tank under the passenger side. Which year model seats (if any) can I install without getting into serious custom fabbing of mounting hardware?
