Thank you Slowpoke, I've been put on to a place in Mitcham (approx 20km's from home) so will give that a try first. The idea of being able to physically take a ring in and have it matched against a replacement is appealing. Failing that, I'll be on to your contact with the following pictorial of what I'm after.Verity Rings
Ring Image - 1 of 2 identical rings per piston. Note bevel on Internal Face.
Ring - Width (between Upper & Lower Side Faces)
Ring - Radial Wall Thickness
Barrel / Cylinder Diameter
Piston Ring Seat / Groove Diameter
Also interesting to note is that although the the Verity and Riptide Fisherman comprise what is essentially the same engine (Riptide Fisherman is a remodeled/simplified for production Verity), the rings on the Riptide have smaller Width and Radial Wall Thickness dimensions.Riptide Fisherman Rings
Will let you know how I get on.
Thanks again & Regards,
