Grubby - thanks. I only have the rear end mounted, but from the instruction manual the engine should mount within about a 4 inch area - so I have a good estimate where the engine mounts go. I just didn't want to keep going with the T10 mock-up (need to rebuild the T10 also). There is a good explanation of pinion angle on the following site
