The Project Pad

I'm getting ready to put the engine in my coupe, and went looking for the 3 bolt gasket between the header and j-pipe. I found the part# on etka, 893253115A, but the cost of the gasket is nearly $50! Has anyone found another gasket that fits here? Wanted to ask before making a copper one.

Thanks for any advice

I may have just answered my own question. From what I have found on eBay(so who knows if it's correct) the BMW 18307830674 gasket is the same. Which I can get for around $10. Anybody have any experience here?
