Has anyone tried using a universal alternator bracket such as the A200 
from alternatorparts.com
I have seen the same bracket on a couple of other web sites as well.  It 
bolts to the two existing generator mounting holes and then the 
alternator mounts to the bracket.  It appears to be adjustable for 
aligning the pulleys.

I did the same as most other seem to have done and mounted the 
alternator at the front generator mount and used a long bolt and spacer 
to capture the rear generator mount hole as well.  This also required 
machining the alternator mounting ear to align the pulleys

My main concern in looking at the picture of the A200 bracket is it may 
mount the alternator higher, I just can't tell how much.
