ADM Losmandy mounting plate hole spacing?

[michaelmorris]

I'm in the process of beefing up my mounting system for my 80mm refractor  I've bought a pair of Teleskop Service tube clamps and want to mount these on a Losamdy-style dovetail.  The ADM DUP11-M looks as though it should fit the bill.  The 60 mm gap between each hole in each pair of mounting holes appears to be exactly what I need.  

However, but before I buy one I need to find out the distances along the dovetail between each pair of mounting holes.  Can anyone help with this?
