If anyone can give me some answers for the questions I asked above, I can get moving on with my potential piston/ring supplier.
Thanks, Dan
Other than someone with a dead/spare engine sitting around, probably Phil Bleazey or M3W Services could supply this info? I know Phil has been looking for some suppliers for unavailable (from S&S) X-Wedge parts. Possibly you could help each other and ultimately all of us?
