Cheers for that Lee. I made a blunder in my mention of the Toyota tail lamp used on a Lotus. The one I saw was on a 1989 Lotus Esprit Turbo.
No I cannot find the link to the aftermarket replacement pairs. Will pass on if I find it.
I reckon I will be able to get my covers looking pretty good. Will post some photos once I get the job done.
Cheers
