I have an 88' K5 350 tbi and I'm considering finding a donor truck with a 350 (89 and later) to take the serpentine belt parts out of. First off, do I need to use the newer AC compressor and hoses since they switched to the passenger side? Second, what all do I need for the conversion other than belt, tensioner, and possibly compressor w/ hoses? Are the pulleys the same? thanks.
