Balmar alternator case

[mdsailor]

Hi guys-
Does anyone know where I might find a replacement front case for a Balmar model 90-100 alternator?  It appears Balmar got these from Lestek Inc., which is no more.  Balmar is only interested in selling me a new alternator. 
I managed to wear the mounting holes big by letting it rattle around on the Westerbeke diesel in the boat for a couple thousand miles, and finally broke off the front mounting lug. 
This is the model with two mounting lugs, about 3-1/4" apart that is usually found on a Yanmar, but a Delco style case with a single 1" lug would work too.
Thanks,
Quent
