I have a full set of TR4A dash gauges (from 1967 TR4A) that I want to sell. Worked fine a few years ago when I parted out the unit. Your guess is as good as mine on current workability. Make me an offer for all of them, what you see is what you get.,(plus a free ashtray). I have pics but haven't posted them yet. Email,will get you pics.
