Mine was the opposite. My car was one rare moose. Came from the factory with a bucket seat Toruqfilte column shift combo, still don't know how many '70 R/T's came with that opption but I know it's rare. Somewhere down the line, like very early changed it to a bench seat and along with the original buckets the BC sheet went.
I changed it back to buckets but added a console and slap stik for fun. Kept all the original parts including the bench seat with center armrest. Like yours but 1970 Challenger style back buckets. Kuewl but I found you lean too much going around corners, plus when you need to adjust your seat that means your passenger has no choice but to follow you LMAO!!
Car is looking great by the way. Keep us posted......................................
