I'm trying to get hold of part number 5 in this picture:-
It is unobtainium at the dealer as mentioned previously so I've been trying to persuade people to let me have a good second hand one.
Not as easy as you might think. (Well who wants a pile of discarded sheet metal on their driveway anyway? Scrap dealer doesn't mind that's who)
I think I've found someone who will let me come and cut one out. If this comes off - and it doesn't turn out to be rusted junk I'll take some photographs of the carnage. It will be tackled in the following way:-
Windscreens out
Sub frame / trailing arms / differential rear wheels off
Doors off
Cut off roof
Slice through middle of floor pan (if rusted out)
Otherwise cut at bulkhead...
...if I get away with this it will be fun!
