Thanks for the message Wil. Close but no cigar. I should really have put more details into my first post.
I have a Jag/Chev 5x4.75" stud pattern.
I need as little backspace as possible (deepest dish).
Halibrand/FIA/BRM styles all considered.
Or I could just stop being a tight@rse, take a leaf out of Gav's book and just order a brand new set...
