So don't. I ran my 73 Eldorado for over 100,000 miles with a worn down
generator support yoke casting. Without the support at the front end of the
generator, vibration will quickly tear the generator bracket to pieces.
Just mount the generator gently and measure or otherwise determine the amount
of slop between the generator and the casting. Now get a comparable piece of
brass of the same or slightly larger thickness and cut a shim to fit in
there. Some snipping and tapping will get it to fit into its curve. If done
well, you can have tabs to bend over and hold it in place. The shim will
securely take up the loose space and work for maybe 50,000 miles. What more
do you want? Let me know if you want a picture and I'll try to draw one.
The big issue is on reinstalling the generator and belt. If you make the
belt too tight, it will crush the brass shim quickly, allowing the generator
to rock and again break the mounting bracket or one of its mounting bolts.
If you make the belt too loose, it will flop and vibrate and set up some
motions which might accelerate crushing of the shim. The loopframe belt
should be just tight enough to not flop around and certainly NOT taut. It
should be nothing like a power steering or air conditioner belt. Just snug.
