I'm looking for some help or pointers for anyone who's seen this done, or perhaps done the conversion themselves. I have a '63 Impala 2 door hard top interior I'm trying to put into a 2 door Biscayne, just because it's what I want to do (back seat speaker covers are awesome). I'm noticing the bottom of the back seat bars that are supposed to hook into the floor, are a good 4" away each side from the floor hooks (there's no good place for them to hook into). I've seen photos of an Impala interior in a Biscayne online, but what did you do to properly mount the rear seat bottom and back? They should technically fit, there's definitely enough room for the interior quarter panels (they're narrower than the sedan seats). Before I get into drilling and installing hooks in my floors, I just want to see what's been done. Anyone who can offer some help is greatly appreciated. Thank you.
