Donor discs for a 66 Valiant??

Went and looked at the 74 Valiant today, car had 48,000 actual miles on it.. Front disc rotors and stuff look awesome, rust free floor pans, perfect dash pad and seats.. To bad it ended up in a scrap yard even tho it was a 4-door... I'm going to get the disc brakes off it and the whole floorboard for my 66 Valiant.. "BUDGET BUILDING 101"!!!!
