1978 Cadillac SDV (Commodore Blue Met.)
While swapping the stock single plane intake manifold on my 78SDV 425 with the stock 500 manifold it was discovered that my AC system is inoperable n needs to have the compressor replaced n system recharged. I plan on fixing this but not for awhile. In the meantime i have begun removing the AC system n all its components. My question is, with the compressor removed i now need a smaller belt to replace the existing one which now doesnt have the pulley on the compressor to go around. Does anyone happen to kno what size belt that would be? Or the proper way i would measure to figure out the size needed? The new one will be going around the power steering pulley n the pulley down below. Anyone who can share any knowledge of experience with this would be greatly appreciated! Thx alot n have a good week everyone!
