dust cover, selector shaft.

hi all,
well i changed the seal on the front output to propshaft of the gearbox, and the gasket on the flange, tight for space there but that all went ell, when tightening the nuts on the flange, it was tight against the dust cover on the ends of the selector sshaf and it appears i popped a hole in it, leaking some oil now, not a difficult part to change by the look of it but, cant find one?!! any idea of part number? or am i naming it wrong?
cheers all
