I am that crossmemberless mate .
Thanks for the help guys. It seems as though I will be making a replacement myself. I'm no expert welder but I can just about manage to melt metal together so what the hell, it doesn't have to be pretty.
It would of been nice to be able to cut it out and weld a ready made section in but I have already come to realise that my Landy only likes to rot the 0.5% of parts that can't be bought straight off the shelf
