I need an exhaust chimney (flange to pipe stub adapter) for my PD-40 stationary engine. I'm hoping that maybe some of the other larger tractor engines (W-40, WA-40, WK-40, WD-40, F-30, W-30 etc.) might use the same size. The exhaust hole in the manifold flange is 2 3/4" diameter and the three flange bolts are all 3 3/4" spacing on center. If any of you have one in your parts piles and could take a minute to measure and see if it would fit this I would sure appreciate it.
Thanks -- Brian
