if you are not running bone stock, I used to do this, I run w/o estart.
Get a 72 or earlier rt side swith assembly..use the starter button for the horn, it has hi-lo-off for the lights, use the mc to hold the mirror,
I studied the design of the lever pivot, it has shortcomings, there is ways to overcome that but a bit more work.
You can bolt a piece to the lever to add support. top or bottom, then run a bolt with a longer shoulder section, to make lever less prone to sidfe movement.. if this added piece is on top and bolted over the clutch cable end blind (from top) hole, then you can remove the fastener to oil pivot end.
Another method is to make a forked pivot end on the lever, and run longer shoulder bolt, that would double the surface area of the pivot and last much longer..
We need an improved version...
