Paul,
In case this bellhousing is successful and others want one I was wondering what size centre hole,
in the bellhousing, do you think appropriate for Tracy's drive or should I just leave it without a
centre hole.

My own drive will be different I suppose as I will be needing about a 4 " centre hole.

It may be easier to leave a blank face and leave other to work out their own requirements.

I looked at your drawings Paul and it would seem that their is a seal on the bellhousing/plate, as
there is a recess for some reason.

My own PSRU will have a flange like the bellhousing, unlike Tracy's which bolt right through,
although there would be some advantages to that - thinking out loud !

I think the blank face is the best approach. Make that part of it about
13 MM thick so there is enough meat to machine it out for Tracy's input
shaft oil seal.
