Hi Lee my 2nd Turbo Optima has very good condition original wishbones fitted which look brand new I think, I was tempted to use them on my Turbo OptIma shelfer but would lIke to help you out....will take a proper look but if so I'll swap you for the mid ones if you like so you can make yours a little more original?
Drop me a PM if you're keen.
Looks great btw!
