I am looking at a Jag front sub frame at the moment at work. Its got some rust and needs modification. Proably going to make my own cross member that I can weld into the front end and take all the XJS arms etc.
Just have to speak to my metal suplier and see if the cross member should be 6x2 box or made from 1/8th sheet metal. I have to drill it, so its not straight forward.
