Looks like this mob have some, just be carefull of the pricing. The price is for one piston only, not a pair.

Id be interested in those Bill I can get rings for them *smile*
hepolite part number should be 11288
I have been told that i can use Shooting Star ones but they are 8.5 to 1 CR which I dont see as a problem

Just been down the shed and checked them, sorry to waste bandwidth but they are A10.
I know I had two sets  of A10 pistons and a set of A7 I got for a friend who didn't use them in the end, I sold one set and thought it was the A10 ones it wasn't as I have two sets of A10s in the shed.
Sorry about that should have checked first

Not sure if these are still wanted and if you wanted them for a long stroke or short stroke Star Twin but I have a pair of +40 long stroke unused Hepolite pistons. They will need rings and pins. John
