Is there anywhere a dimensioned drawing or XY list of the pump locating bolt holes? I am looking at securing the pumps to a hidden plate in the pump box to hopefully stop them moving around and enlarging the holes in the base timber. I have taken measurements from the existing base plank and the pump box and will use these to trial the idea on a sacrificial bit of 8mm alloy flat, but if there is already a recommended set of dimensions I would like to compare.
Cheers

In the past, I have done the same with a metal plate, but by using the pump drive arm fastened the the pump "H", then centering the pumps locating holes on the pump drive's travels on the pump pit floor.
