M20E- #4 exhaust riser- PN: K630045M-513

[MB65E]

Thought I’d throw it out there, my exhaust riser has cracked again. I’ve welded it a few times but I think it’s exceeded its heat cycle limit.
Wondering if anyone has a spare riser collecting dust. PN K630045M-513
Made by Kinsley Exhaust. Now acquired by AWI. It’s the No. 4 Riser/Stack.

Thanks!
