What are some more Chevy truck restoration companies/sites?

I know of the usual like LMC and Brothers, but Im looking for an A/C vent for my 66 that nobody seems to have. I have noticed that some companies carry parts that others dont, so Im wondering if maybe someone does remake this part. Thanks - Brandon

You might try.."American Classic Truck Parts", or "Jim Carter". I think they both carry parts for 60's chevys.
