I finally got my 56 - 62 Cadillac header flanges dialed in. I will be ordering a pair in stainless, 1/4" thick. They will be laser cut by a company called "Send-Cut-Send" in Reno, Nevada. All you do is upload a DXF file to their website and in seconds you can get a quote in many different materials and thicknesses. 1/4" carbon steel are $27.00 each, 3/8" are $37.00, 1/4" 304SS are $46.00 each and 3/8" are $68.00 each. Shipping is free and I have never had an order take over 10 days to my door. Here is the deal, I am not selling the flanges but if anyone wants to order a set, I'll email you the file for free, nice guy that I am. The photos are a test part done in 14 gauge stainless to make sure it was right first. Jon
