Thanks for the advice and the welcome message. The problem for me is that unless and until I get the car I can't be a full member so I don't have access to the "wealth of information" or the shop.

The link to the place in Brighouse is interesting and they aren't too far from here. However I generally like to do all work on my cars myself.

I've seen the repair with just welding in the tube, but I'd like to take the opportunity to overhaul the whole back end so I may as well take the whole thing out. I'll let you all know what happens!
