Well according to the http://www.precision-devices.com/asps/uploads/super/3.pdf - PD data sheet (picture at bottom right hand corner) it's 414mm. But don't quote me on that.

I've checked an older data sheet (from when PD were in Cornwall), plus 3 other PD 18" that use the same chassis and all state 414mm hole for front mounting. But they could all be wrong.

When I built mine a couple of years back, I used the measurements off the manufacturers speck sheet and they were fine!
