Paul,
Will there be enough material to the lower pivot to press in some bronze or steel bushings ?
Also is the width of the lower pivot the same as the alternator?
...Chrissi

Yes on the bushings. Depending on the size of the bolt of course.
I doubt it. I made it quite generous but probably not as wide as
an alternator. On the order of 3 or 4 inches. 90% of the belt tension is 
taken by the lug closest to the belt and that is beefed up by  a solid
chunk of aluminum. The back end of the lug is beefed up by two
hefty ribs. The back part can be spaced out to be the same as the alternator
if you wish. You could also tig weld on an extension if you are
worried about it. I am not.

BTW steel bushings make the most sense but when the bolts are tight
they should be unnecessary. Bolted joints do not transfer all the load
through the bore. Some of the load is transferred by friction between the bolt
heads and the nuts and the lugs.
