Then why are people constantly asking about drilling out the pushrod hole?
They even make a...
They aren't completely "lost", Photobucket disabled free image embedding through third-party sites (hotlinking). So the threads here with his embedded images are broken.
A google search for M21RSZ28 pulls up tons of his photos...

If you remove and replace it (and if...
