Six Shooter, I will give things a week or so to see what comes of Scoota G sourcing some locally.
If all falls through here, then I am keen.
I had no idea these were intriguing, As far as I can tell, the set I currently have are the early 240z type.
...And for future reference, I will post up pics of the swap. (If successful, & once i get it sorted out).
Thank you Scoota G, you are an absolute legend. (He has been looking through his workshop and mates places trying to help me find what I need).
