I have a ‘68. It’s dual badged both Chevy II and Nova. And a giant PIA to get parts for. Lots of ‘68 only parts. Buckets, seat mounts, steering column, heater controls, front fenders and market lights(smaller), door panels(cranks are 1” out from 69-74), some chrome trim, clutch/brake pedals, ... and that’s just what I’ve found so far. Oil pan is notched for rear steer cross member. Center console was 1year I believe. I got lucky on a set of buckets and the seller realized what they were and tried to back out of the deal.
