I have for sale a M122, I bought it to do the swap on my L but decided to go a different route. When I bought the seller said it had been ported, I cant figure out how to post pictures so upon request I will send pictures via pm or text which ever you prefer. You can clearly see it was a home port, and not to much done to it. To my knowledge the blower has 40k miles on it. 400 plus shipping.
