Anyone got a Sag rear upper wishbone I could borrow?

[gmw9666]

Hi all - in my previous thread http://www.pistonheads.com/gassing/topic.asp?h=0&a...

I think I have sorted my wishbone problem out........but I still need to sort the upper rear wishbones

Would someone have one I could borrow (i'm in the midlands) or at a minimum share some dimension

Dom at TVR didn't have one in stock so need to try before I buy
