When I converted to a single,points system I had to install a dual output coil. I opted for a Honda 750 coil and welded tabs on the frame on which to mount it.
The coil lasted all of two weeks, so I ordered another the same and installed it. It's still ok, but I have heard this particular coil is known for a short life. With this in mind, I found another type, still for a Honda 750, and ordered one. When It turned up, I discovered it was about 20mm longer than the other, so, the tabs I welded on the frame were too close to allow fitment.
So, I cut the rearmost tab off the frame, jumped on the mill and machined this bracket. The bracket clamps around the short frame tube under the main top tube and can be slid forward or backward to fit either coil.
