Ive got hold of a Snap off boss made by Mountney. It fits my Momo Steering wheel but not the Momo boss, PCD's are different. So do Mountney bosses have different PCD's to Momo? And wheres the cheapest place to get hold of one???

I guess I should also add are they collapsable like the Momo bosses?

If you happen to be passing it's always worth trying the Halfords discount bins. I got a Sierra one for a fiver in there.
