If you've got your catted pipe out and handy, can someone measure the diameter of the O.D. of the pipe where the flange bolts to the header just before the flare? Preferably with calipers.
I'm trying to put mine back in for smog test and the PS side flange rusted away. I don't want to buy a new one just for inspection, I like my O/R pipe. I figure I can make one, cut it in half and weld it together on the pipe. I tried one at home and it just about worked, too thin material. I thought I could get the dimensions off the old flange at work (machine shop) but it's just too distorted to trust.
TIA
