we picked up a 72 chevy van 20 for our band va. the brake booster is going bad in it and i was wondering if anyone new what other truck these parts are compatable with. the people at the parts house look at us like we are stupid when we ask for parts for this thing. is it the same as the 3/4 trucks? i need to redo the carrier bearing too now and they cant come up with one. any help would be nice. thank you.
