Bruce Young of Y Block Magazine used to make flanges, If there is enough interest, I can make a few sets, ether round tube or square.

Speedway makes them $50.00, however their 5/16 thick

I’m having them water jetted locally from stainless to work with a pair of stainless small block scruby t-bucket style headers for my Model A hot rod build. Should be done in the next few weeks. bought a pair of flanges on eBay a couple of years ago for another header build I did but they were mild steel. Worked ok. MIKE

Mike, still lovin his 57 t'bird after 53 years!

Joe, I don’t think the Thunderbird headers will clear the motor mounts on a passenger car. They also have a welded mount on the header that picks up the “steady rest” side bars. It’s all damn tight installed, and the oil filter is a b.cth to change.

FYI on Speedway flanges… they happened to be 3/8” thick. Their listing does say 5/16” but the ones I just purchased and had shipped are exactly 3/8”.

Look to be well made but anyone else use the flanges from Speedway also?
