Subject: Re: 2L LC SC rewire
A firm called Autosparks manufacture wiring looms for our sort of cars. They supplied one for my Riley RMB, and I'm likely to go to them for a replacement for that on my V12 ... especially as none of the VSCC member/specialists have shown any interest, just wasted my time!
If they don't produce one for your car, I believe they will copy yours, with any alterations you require.
