The new stand fits very well. I was going to make a jig for John to help when he welded in the pivot bracket, but he said "don't bother I'll just hold it position myself" It turned out absolutely spot on. It has a nice line parallel to the swing arm and the spring has good clearance with the tyre.
The springs look nice now that the're chromed and I have a new chain fitted over the old sprockets, but they were ok. The tensioner and torque arm have been zinc plated.
