Hi Can anyone recommend someone that can do a good price for fitting a rear crossmember for a 300tdi near to liskeard cornwall happy to travel 50miles plus in either direction?

Clive at Blacksheep.....but you'll have to be quick as he's retiring. He will also supply you with the best replacement crossmember on the market at a fraction of the price.

Search on her Blacksheep or Pressbrake (one in the same!)
