164 rear cross member repair
i have a black 1995 164 cloverleaf, and the MOT people don't like the rear cross member which they say is buckled, (ie up towards the plastic petrol tank) and a little corroded. I have purchased a replacement one from alfa rusper (near gatwick), rust free, and it looks exactly the same. should the rear cross-members be absolutely flat, or curved slightly on the underside? also, does it matter? i can have the crossmember pressed flat and then welded up again, with thicker metal. if i have the second one done aswell, is anyone interested in acquiring it as a spare? they don't seem to be available new anymore.
