k how bout 80 bucks plus shipping
John

did it come from a ton truck confused: because i haven't seen this on a 1/2 ?is it any good because i can buy a new one from auto parts for less, it is a 72 but it will fit a 62-66 chevy or gmc that i know off, :D

Yeah it came off of 1/2 ton truck, so that is pretty rare in itself I dont doubt you can buy the power brake booster for 80.00 for a 72, but this is in ORIGINAL power brake setup. This boosters seem a little smaller than on the 67-72. plus the brackets are a different as well. So i dont think 80 dollars is out of the question
John

i guess the question i should have asked was did you take the brake booster off the 65 yourself or did you purchase it haveing been told that it was on a 65 gmc

Yep I took it off myself so i am almost sure it is original unless it had been modified but i doubt it.

k 60 dollars plus shipping, as low as it goes.
