The rear lenses are interchangeable from one side to the other. I have one in a box that has a slight bit of damage, but is otherwise pretty sound.
I'm open to sensible offers...
Thanks so much for responding, about 30 minutes before you would have posted I bought a lens from a Jensen restoration garage as apparently they are the same as used on the MK1 Interceptor. The guy assures me it's the same, but I'll see when it urns up. If not, I'll be straight back in touch to see if you've still got yours, thanks!
And thanks also for the steer on the wing mirror. I've been looking at loads of Coupe PF photos to see if anything was stock or standard and it doesn't really seem to be, so your advice totally bears out. Mine is currently black, but I think it looks out of place against all the other trim on the car.
Cheers, really appreciate the response!
