Restoration Fan belts for 1973 340 Roadrunner

[Builderguy]

Spent the last few hours looking for the correct looking alternator belt and the power steering belt. I can find them for 1972 and earlier but not for 73. There are plenty of top cog and bottom cog belts available but these are not period correct. Anyone have a source?

Looks like I will have to get the standard size Gates V belts.

Well that is not going to work, way too wide. Need the belt to be 13/32" wide not 21/32". Back to square one.
