Hi all
I have purchased a replacement cross member for my defender from Mr Pressbrake
The vehicle has been completly stripped so it will have to be done on site

I need this doing asap as it is holding up the rebuild

if anyone can recommend a good mobile place please let me know

Having never welded before its not something i would like to attempt

where abouts in Cheshire are you.
