Just to update, one of the members here has been able to offer a lhs body that I will work out well (the escort also has one of his 'Sport' instrument clusters as well, but RHS bodies are less on the ground at the moment.
I found some light seals on EBay Uk through Motomech, if anyone needs some.
By the time this car is fully sorted, I reckon it will have bits from pretty much everyone on here.
I'll post some updates on a thread, as there's some bits of the car that look a little ok if you squint.
Regarding the swap, no sorry can't help I'm afraid. I do however have 2 unused OEM electrodice modulators going cheap, one has only been taken out of the box for photographing.
Happy to swap it for a 4 spoke mk2 rs steering wheel.
