I have a belt slippage problem on my 55 F-100. I am not sure how to route the belts. I have added a crankshaft double pulley giving a total of three grooves. Power steering brackets (by John Mummert) AC and alternator bracket from Vintage air w/Double pulley. G.M one wire alternator w/double pulley.

Stock there were a couple different belt widths, depending on application. Mixing pulley widths would be a problem, especially with aftermarket pulleys. Old belts can get hard, or glazed. Many brackets require some shimming to get the alignment right. Any mismatch here could cause slipping.
I don't know about trucks, but generally the one belt is crank-gen-water pump. The p/s is crank-pump.

Thanks for the info. All pulleys are the same width except the inner crankshaft pulley. I didn't consider belt width.
