I recently purchased a new mast base fitting from Bob Keeley (ex Ronstan casting)which has a pivot point a bit further rearward than I had seen on the newer base fittings. The design won't allow drilling further forward because there is limited thickness and just won't provide enough strength.

While this will probably be a good spare I would like to get a newer design base so that I can drill and tap it further forward to provide more consistent mast rotation especially when running or on a broad reach. Does anyone have a contact for the newer mast bases ? Any feedback would be appreciated.

I would also like to get a good set of new spreaders as seen on the most recent builds. Would these also be available from the same source ?
