Well according to the 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.
If it's got wheels or tits it's gonna cost a fortune

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