Hi
I did a bit more measuring and ended up dropping the gearbox to line up with the diff. Apart from anything else, I found that if you don't do that then the front of the engine sticks above the natural line from the nosecone to the scuttle.
As I haven't finalised the engine mounts the only change I had to make was to drop the gearbox mount to the bottom of the transmission tunnel. The difference in height is now so small that I can't believe it will make a difference. Downside is the bottom of the gearbox is below the bottom of the chassis, and the bellhousing/sump sticks down quite a long way so will need a fairly major chop.
Mike - I've been in contact with axle, and he's been very helpful and sent me some pictures that didn't really make complete sense until I tried it myself. I do have the engine in line and horizontal so that's one less thing to check.
TT - From looking at the website Mike posted, one important consideration is to have the input and output flanges parallel so that's what I've tried to do. Angling the diff would have meant they were at different angles, and I'm not sure what effect that would have.
Thanks for the help
Matt
