OD top cover

[Don Malling <dmallin@attglobal.net>]

List, 

I am converting my TR250 to an A-type OD. My existing non-OD top cover
appears to have "blanks" where the two OD switches go. Do I need to buy
a new top cover or just drill out the blanks and maybe thread them? The
transmission is at the body shop so I can't go look at it (whether the
single existing switch has threads).


Thanks,
