|In the past DC sold Adapter for the frame. Since 1985 i rebuild them by myself. With these adapters you can easily place the G on supporting posts. I thought this might be helpfull for owners of a 460. Attached some drawings for the adapters. You can make them out of a pipe (0,2 inch wall thickness) with 2,4 inch outer diameter. The 45ï¿½-chamfer allows you to insert into the frame pipes. In the front you'll use 2 short adapters (6 inch long) and for the rear two 12 inch long adapters. For orientation a flat piece of metal will be welded to the pipe on the longer side.
