I haven't got any to sell Joe, but I made both parts for my car as the originals had gone rusty. They are very simple to fabricate and I can post dimensions if it helps. I made the front one deeper and a slightly different design as I used to get crazing directly above it, but with the later design the stress is spread over a greater area and no cracks yet !
The only thing I struggled with is the rubber boot that goes in the front catch. It stops water dripping down onto the locking bar and into the car but of course mine had perished and I haven't seen anything like that for a long time now. The best I can do is to try and channel water away from the locking bar.
The locks themselves are still available, I think SJS list them on their site.
