Hi Fil
As you've got them, I'll buy the rear stops from you

Pm me and we'll arrange it when its' convenient for you.
As for the lift - I can replace the rears - it doesn't look too hard (famous last words) but having seen the procedure for replacing the front - that's going to be a dealer job. I park in my street and I don't have access to a garage and I REALLY don't fancy doing that replacement in my street, with the traffic we can get and (very probably the way this year is going) in pouring rain!
I will take pics when its done and post them up here.
I'll be sticking with the 235/70 R16 tyres - the size is handy, and I'm happy to see space above the tyre when the lift is in, and I don't want to add more to the unsprung weight than is already there; I don't want to get toward regearing territory either!
