Yeah, Dad had a local Ford dealer make him a "DEAL" on a 78 F600 and F250, that was so good he switched over from Chevy's. Dad gave me the old Chevy C30 12 foot stake body when he retired in 86. I took it to the auto parts store because the fan belt was all shredded and getting ready to brake. The guy asked which one I needed? I said there is only one on it, gets the fan and power steering pump. He argued that it was a 72 so it had to have a smog pump. I said nope, not on the C30's and up. He finally walked out and looked, one belt and no smog pump.
