Never in the years of owning my Z have I ever been pinged for no TBL and that includes rbt where DOT have gone over car, I think the ADR came in 89 so unless your cop is a complete douche and knows every manufacture year and spec of every car your pretty safe
Just put a third brake light in the window. Takes like half an hour and you can do it so many ways. Thats what i did.
Mine Mine was welded up when I bought it - with a F40 wing fitted. Had the F40 wing off at one stage... Just looks odd to me. I had to cut a section out to fit a modded 89-93 spoiler. TBL was in the rear window.
