piloon-yeah,been thinking something like that,was checking online-site named " thecvman " gonna have to get under and take some measurements,I have an outside caliber that will make short work of the measurements then the hard part,trying to match one up.
Also thought about wrapping rubber around it but not sure if the clamps will hit while turning,even thought about buying one from bota for 2.50 and cutting it,then contact cement.
****,aint it a *****,one way or the other is going to be a pain in the ***. Love the bota though!!!
