Hi,
I was stuck in the same boat as you looking for one, it took me 6 months of looking and finding nothing... then as I sell the car magically 2 pop up here in New Zealand....
Your best bet is to look for someone wrecking a 260z but expect it to have some normal rust, or PM nat0_240_chevZ he had a post up a few months ago about making them.
How bad is your one?
