I think I used an 8mm one, drilled all the seat brackets out on mine
Get a drill with variable speed and use it on slow in pulses though - they're sharp as hell and go straight through the french tin can body work in seconds
I thought you saved your special cuddles for me?
It's definitely an 8.0mm mate. We stock them, and i'll get you a handfull if you wish?
Ideal! I'd give you a reach around if you did...
Pmsl! I'll try and get some tomorrow if I remember mate.
