Thanks Norm,
Worth trying to see if it is possible. From your photo it looks like only the area in and around the Briggs bolts is thick enough to re drill so we might have to be lucky for it to work. I still do not know if I need it yet as the pulley is still waiting on lathe tools from China. I think I will because the FC needed spacers and FC's and PT's are the same shaft length.
Thanks for the offer to post one. Pretty hard to come by an ally one these days I would imagine. Lets see if its needed.
All the best
