[67rs6spd]

I'm looking at a 73 ta owner says all oringal # matching!He is the 3rd owner 15 years,and his friend had the car for 10years.This is all I know for now,motor ia a ZZ 455 should the #'s above match the Vin?Non A/c.4 spd car,should it have a m22?The rear looks to be a 10bolt is this correct for a 73 TA?(to much snow to tell for sure)Can some one give me the codes for trans and rear.The car has surface rust on the trunk and roof,rust in lower fenders,Qpanels have rot on the inside area where the trunk bumpers hit the Q,only floor rot is on drivers floor.clean title cars has 90k on it sounds good,can't drive poor brakes.He's looking for 3k car is all together what do you guys think.
