...These are reference photos I recently took of some of my 906 pistons and cylinders. The plan is to send them to Ollies for the modifications and cosmetic treatment. I still have to figure out if I'm missing some 906 P&C's, if Bernie has a set or where they are. I purchased one complete set from Bill Noon (but missing one 906 piston from the Noon set), and also purchased a 2nd set? Maybe 906 cylinders ONLY, not pistons? This is what I have to figure out.
