Chris, apologies for the delay, life kind of changed my plans for me over the past 2 weeks!
Im having a play this afternoon, do you still need these dims?
Cheers, MM
Don't go out of your way!
I've been too busy to approach this project for a while... but very a rough check with the dimensions you already provided shows that the early and late mounts are likely the same in the critical spots, just rotated 90 degrees from one another.
Thanks
Chris
