TCM cylinders

[flyer170]

I have a friend looking for a new TCM cylinder for the 0-300 would anybody recomend a source to purchase one
As a side note this fellow lost a cylinder on an old straight tail 172 with the 0-300 and guess what happened Yep the rocker arm bosses broke
That is the 3rd airplane in 2yrs and 4 cylinders that the same thing has happened to, that I know personally and I don't get around that much.
