I bought a seitech dolly on Craig's list. Seller did not know what boat (laser, sunfish, etc) it was built for. I can tell by the measurements that it was built for a much larger boat than laser or sunfish. I'm thinking of modifying my dolly for a sunfish, but I cannot find the dimensions for the aluminum parts on line (axle, centerline support, stanchions). If anyone has the original packing list from a seitech sunfish dolly, the dimensions are listed with the parts. Could you take a photo of the parts list and post a reply. I would appreciate your help. Thanks.
