I was refitting my drivers seat after fitting harnesses and have inadvertently stripped the thread in the chassis crossmember that the allen bolt for the seat rail goes into. This is the one for the front left corner of the driver’s seat.
Actually, it turned out to be an easy fix. I bought a tap and die set, and was able to tap out the M8 hole as good as new, and the original bolt fits snugly and is just as strong as new.
I could not have bought the new chassis, cos I could never get the wheel arch liners off anyway!!!
