You know the sort an approx 6" round vinyl covered pad with a captive threaded portion that you screw into a captive nut / rivnut on the rollcage bar behind you head so you don't hurt your head / helmet (oo-er!) if you have a shunt etc?

Can't be bothered to make one so was hoping to buy one.

Anyone know where can I buy one?

Theyd be sod all to make. A square of wood and some foam and a bit of vinyl and attack it with a knife and staple gun.

Sylva sell them for the riot for £58 a pair.
