How useful is a '73 parts car for a '71 resto?

[RoadrunnerSteve]

I've reviewed the technical articles here and understand that most of the body is not compatible, but what items pulled from a '73 satellite would be usable on a '71 RR? Bench seat? Wiring? I'm an A-body guy and need to figure this B-body stuff out...

I grabbed up a bunch of interior and internal parts from a 73 SSP for my 71 SSP. Many of the internal body parts, ie floor/trunk pans, cowl area, etc are similar or the same. Door regulators, bottom door panels, glass, windshield/rear window trim, dash parts are all usable. Some stuff is not 100% correct, but will work. Generally a lot of good misc internal parts if you are starting from a bare shell. Then you can part out the incompatible parts to recover some of your investment. Some main parts that are not the same: K-member, front suspension, inner fenders, all front sheet metal, quarter window trim and upper panels, doors, rear sheet metal and bumpers. I believe benches and buckets from 71-74 all mount the same, just won't be correct for the year. Someone else chime in if I missed anything or if I am wrong about something. Good Luck!
