I see. Thanks. I was only basing my guess on the fact that the top bolt on the door hinge plates is missing the steel of the chassis so I assumed the whole hinge post and 40x40 crossmember was lower on mine.
The only welded joint I will have is where I graft the inner column into the adapter and that can be pinned too so, for me, it's not exactly a 'cut and shut' with all the connotations that implies.
