I was fortunate to find a muffler shop (family owned) since the early 40's. The son running the shop dug through a lot of stored boxes of old records and found the card for my 46 (216) bent the pipe as per the numbers and it bolted right up.
These are still out there you just have to keep asking. Modern chain muffler shops are of no help with our old iron! I guess they could measure and bend something to fit.
