You were quick off the mark there Abyss! Gave them a call earlier to get an idea on availability before ordering online (need an excuse to stick some rbf600 in that I've had on stand by for a while). Was told they'd be made up by Goodridge, should receive next week, saved a few quid on carriage by calling and got them in red
I'll measure them up when they come through, pretty sure they'll be the same size as the 156's (& GT?)
