Sounds like thats what my problem is,wrong rack, but it does'nt do it on the o/s/f. I'm thinking if i screw the n/s/f trackrod end onto the rack as far as it will go & do the same amount of adjustment on the o/s/f to lengthen o/s will it not shorten the lock slightly on the n/s & increase it on the o/s ?

Failing that i think i might have to take a sledgehammer to the inner wing
