"Whose this B210, prepped with cage, wheels in air driven with rage........... Kerb killer, Kerb killer" or so, he song goes or something like that.

As someone who pounds the kerbs mercilessly I can respect this. I also feel your pain on gearboxes, currently my 60 series 5 speed has been fine behind the A15 but it appears I'm going down the route of a 63 series box. Long term the goal is to find an A10 510 with CA20 power as those gearboxes have a 1.9 2nd gear.
