Anybody know of, or ever dealt with these guys...

The guy's name is Mark Wilson, and they link to Coenr Carvers from their website. They appear to be oriented toward Mustangs, but had a great price on a Canton oil cooler kit for Fbody,

I ordered some parts from them, and they readily accepted my paypal, but now they don't respond to my inquiries.

TIA
