Jeff - Had a conversation with a fellow two days ago who bought a grille from I & I about a year ago. He bought a stainless steel grille and says it is as near to perfect as he could have hoped for.
I'm not sure of this, but I think some of these reproduction parts are done by one of the vendors than the others buy from the vendor who makes the part. In other words, I think I & I is making the grilles and selling them to Jim Carter, Chev's of the 40's, The Filling Station, etc. at a discount so there is a profit in the part for the vendor. I could be wrong, but I don't see everyone of them making grilles.
I would still buy from I & I. And I don't see some overseas factory making the grilles and selling them to the vendors.
