Thank you for pointing out all the things "Not original"...Good eye...in typical fashion the original interior degraded away and he changed out the items with a 71 that he had but he saved all the original parts so they can be reconditioned. The original owner saved almost everything right down to the AM radio,window sticker and original bill of sale...also got a truck load of parts with it...2 440hp blocks date code 67 and 69, 426 max wedge block date code 64 and stage 3 crank, 71 challenger dash pad 71 rally wheels extra 6 pack air cleaner and set of carbs 8 3/4 side clutch center section...ect.ect.he had been a mopar mechanic since the early 60s and collected all of this stuff over the years...the 426 crank is still in the original cosmolyene....all cool stuff
