That would be amazingly simple. Here's what I bought from Autozone. Where and how would I get a wider belt?

The one I bought in the attached pic is 0.44" wide. Autozone has one the same length in their 17 series that's 0.53" wide. Classic Performance only sells one that is 0.469". Wondering which to get.

Originally the belt widths were 3/8" (.375") for alternator and 1/2" (.500") for the PS. (I think anyway)


Now they are probably made metric.
Try and get close to the widths for each one might help?

Get the 0.53" wide belt.

Here's what I'm using on my 73 455:

Vbelts

Alternator: Gates 7490 – 49.0”

Power Steer: Gates 9530 – ½” X 53.375”

AC: Gates 7585 - 58.5”

I tried the wider belt but can't get it to go on all of the pulleys. It sits too high. Can I just get a bigger diameter than 51.5"? Only need about another inch or so. Maybe 52.5 or 53"?
