got them on my BB
try flipping it over and use the single ear as the pivot point
thats how i did the one on the 440 with the MH non a/c brackets
fine tuned some spacers and lined the double groove right up
moved the batt wire out away from the head,so no grinding like some of the older posts talked about
i did add a couple inches to the adjuster swing arm with a bend so it would not hit the alt case
let me look I have some pics on a post and pm that was sent to me for a sb IIRC
goody had a good write up on his on the sb,think he gave me the tip to flip it over
the archives have a template you print out for a sb also
i got a couple ruff cut ones already done,need a good clean up and some finish grinding,want one?
