Nice pix.

I'd be worried, however, about all the washers for depth. Not possible to
build in a bend to the tightening arm to bring it flush to the alternator?


It's possible but I'd need to disassemble part of the heat exchanger
to remove the adjusment arm, bend it and reinstall. What I've done
since the pictures were taken is to replace the washer stack with a
solid steel spacer. I've also replaced the original bolt with one
that is longer so that it now projects all the way through the
adjusment tab on the alternator, backed up by a grade 8 steel washer,
lock washer and nut. The whole assembly is extremely rigid with no
hint of vibration or flexing.

I would watch the grade 8 for looseness. May be to high of grade bolt, may
need a grade 5. To keep a bolt tight, you need to stretch it a little. In
the elastic range and not the plastic range of the metal. Grade 8 bolts are
hard to get a good stretch on. I would at least go with a nyloc nut.
