That was me and the number I was given was for a totally different company and the correct company appears to have folded.
However, I have made arrangements to "borrow" an original Hughes Engineering Rear Brace on a short term basis so that I can get a local Rally Fabrication Specialist to have a look at it with a view to manufacturing something very similar.
I'm aware that there are various new models of rear brace that have become available recently however I prefer this original design.
If anyone on here's interested, I'm happy to update on here in the next month or so.
