Terry,
I had the same problem as you with my TR3A alternator. I broke one
adjustment bracket once and also broke off the bolt that secured it another
time.
My solution was a solid lower attachment, same as you are putting together.
All you need is a simple piece of pipe between the ears, doesn't need to be
welded, just the right size so you can clamp down the lower mounting
tightly. I would think that even an old length of copper plumbing pipe would
do. Mine is aluminum but anything will do fine. The trick is to have a very
solid lower mount so the alternator doesn't vibrate; mine seemed to develop
a vibration at a certain engine rpm before I added the pipe.

Subject: [TR] TR3A Alternator conversion bracket pipe
When the snow clears a bit this spring, I'd like to beef up the alternator
conversion by welding in the pipe between the ears of the bracket. This
measures to be 3/8ths ID, 1/2 OD and about 4 inches long.
How does one source that? Haven't found it at Lowes or HD, and I'd hate to
buy a 24 inch section, but will if I have to.
Also, I'd like to use the 2" x 2" steel box to enclose the flange on the
alternator to complete the set up. Any source ideas there?
Remember Claire's "Where's the beef?" I don't want another problem with a
breaking bracket on the alternator.
One thing I CAN promise, the weld on this bracket will be the ugliest piece
of art you've ever seen!
Appreciation in advance....

have finally stopped calling, and where my toes are healing from tripping
over hopefuls)
