Frustrating for sure. I have a Vintage A/C setup. The guy who assembled my engine spent about 8 hours trying the pile of different spacers to get things lined up. He said the instructions were minimal and what they sent was a box of spacers & bolts with a diagram of how to route the belt. The install is not for the faint of heart. I am not thrilled by the fact that the setup only allows for one belt to go around the crank/compressor/alternator. It squealed terribly at first then I changed to belt to a "top cog" type that fixed it. Would much rather have two belts like the OE setup had.
