V6HQ, The rear panel was replaced because the old one was a bit rusty. The original one had deeper pressings.
This one is a rare spares one and fitted great ( hopefully the rear window will as well. )
I also replaced the side return bits, they were not as easy b ut turned out OK.

Boalsie,
Will post a photo of the one I've got and would appreciate any help finding another one.
Do you know Buddah in Alice?

And thanks for the encouragement.
