Hi Ade,

I had a mini catalogue a while ago which listed an LCB Y peice with a boss
for mounting a lambda sensor. Unfortunately I can't find the catalogue
anymore, but I would suggest you try the usual big suppliers MiniSpares,
MiniSport, MiniSpeed, etc. I bet you non mini owners just can't believe the
cunning originality in these names ;-) Or maybe even try going directly to
somebody like Maniflow. Either way it would be cheaper than wrecking a whole
LCB.
