Arizona Moparts thumbs up!
I emailed Martin Kolner of Arizona Parts yesterday to inquire whether he might have a rather obscure part that I need to complete my '62 Valiant resto-rod. I didn't know the part number, although I had been trying to figure it out for a long time. Martin replied almost immediately, and although he didn't have the part, he gladly gave me the part number and I was able to find it on partsvoice.com! Try that with Mitchell Motor parts!
So I think that Martin is a really nice guy.
