I expect he'd sell the SSA a set.

I went to his site! Nice! And, the first thing I see is a sand rail! I'm working on my Myers Max Dune buggy right now. Just built a 2110 CC VW engine... That is some impressive CAM designs.

I don't know what the SSA has, or anybody else here in the USA. Somebody chime in if we are doing this in the States...
