Help please. The plan is to use a 4th gen interior when we locate a black one. Meanwhile we would like to order a bunch of parts including the deluxe front door panels and rear 1/4 panels to get a discount. The problem is we dont know if the width of the 4th gen seat will fit with deluxe rear panels. Does anybody have this setup installed in a 67? I couldnt find any using the search function, just '69s. Or if possible can someone measure their 4th gen rear seat top and bottom. Thanks!

I don't have the measurments of the back seats any longer but it wasn't close. The bottom of the rear in the 4th gen is 2 cushions and the hump is carpet so if using them in the 1st gen, imagine sitting on 2" of foam the floorboards...

Ouch, good thing Im not planning on sitting back there. Is the 4 gen seat narrower?
