Whoops !
I take that all back about the L shapped battery hold-down bracket if it's a
WESTY with screw-down metal battery cover. !

In any case the thread used is ....
M 8 X 1.25.

For a screw-down battery cover , the bracket fits within and under the
battery cover.
( the L shapped one is for a hinged non-westy battery cover )

the kind for  a Westy screw-down batt. cover is flatter, not L shaped in
side view at all.
more flat with a wiggle.
about 1/4 inch thick, about 4 inches long, fits down alongside the battery ,
and pushes against the lower lip of the battery, and is held by  bolt at the
top.
it's all a pretty tight fit too.
kinda fiddly.

Sorry of the misinformation !

Scott
