[TR] TR2/3 alternator conversion & belt length.

[Angelo Graham]

Hello Listers:
Just finishing up an alternator conversion - used a generic AC Delco 
7127. I used my old generator pulley with a bit of machining on the AC 
Delco. Tried to fit a new belt and far too short. Pulled the alternator 
as close to the block as possible and still many inches short.
Not sure if this is a "standard" problem, as the larger o/d of the 
alternator requires a longer belt?
I had a new Gates segmented belt (groves cut across the belt width). 
Just wondering how common 3/4" belts are in various lengths? Anyone have 
a similar issue using the stock pulley and an AC Delco? Any idea of the 
belt length required?
Thanks for any help with this.
