I don't suppose anyone has one of these fittings lying around or know where I might get one? This one has seized onto a tyronsea base and rather than put the hacksaw to it thought I'd see if anyone had a spare 
The aim is to chuck it on the bottom of a euro pin base.
Hi, i have had 2 cobra raceboards, the earlier one had a fanatic track, is that what yours is? If so, might be worth searching that.
Guess it would help if I showed the other end of the equation
I'll poke around for Fanatic stuff, thanks Doug
