That will be interesting to see how they line up but like you say it's a great start and a good solid point to work from.
I think fine tuning should not be too much of a hassle as I have the tools available to achieve those adjustments.

The ED80 should be here on Tuesday so I will be able to fit both up and see what has to be done.
Wish me luck that I don't have to reinvent it to get it to line up.
