Bit late with any replies...been busy....
Where from and how much, well there you hit the problem !
There from Gwyn Lewis, but as far as I know he dos'nt make them anymore :( ,
there an absolute git to make all box section, no folded bits here, and take ages to make to boot, I believe he has some ready to make up but as to if he "will" I've no idea :?: , hence the right place right time comment....Cheers Paul :D
Cost, I believe they were £450 plus Vat... :shock: .....due to the man hours put into them
he also does them in kit form to weld up yourself...give him a ring if your interested, really nice guy and approachable
