Hi
Good luck with your chassis swap, I started mine in mid october and its nearly finished! just a piece of advice... it makes life a lot easier if you get stocks of replacement bolts nuts & other fixings, then any stubborn bits can be ground off quickly, the chassis brackets and tub are mainly M8, M10 and M12. there are some wierd sizes in there aswell so I keep metre lengths of M8,10,12 coarse thread stainless studding, that way i can make a replacement bolt for length. just make sure that they are all at least 8.8 stamped, (more for things like recovery points etc..) finally go to your local chinese takeaway and eat sufficient food to provide lots of little boxes you can put screws etc in!
HTH
