Gary Landes - Rover Works. http://www.landrovermd.com/
Search this page to see the job he did on my truck. Maryland is not too far to come for a great job and a great price.
Are you sure you even need your Rear Cross member replaced? It is amazing what he did with mine that I thought I would have to replace. Search past post by me and it will not take long to find the long thread on the work done to my truck...........
