Can anybody tell me positively if the pistons for the 026 Pro and the newer MS261 are the same and will interchange? It appears that both are a rather odd 44.7mm, but I'm not sure about the skirt, wrist pin diameter, etc...or any other differences I can't think of. I can't imagine they would be different, but want to find out before I buy an 026 Pro piston to fix an MS261 I just picked up for $80 bucks...any help/advice much appreciated...
