I got a new cap from Victoria British a couple of weeks ago because I had been using the "non-concours" 4 ear replacement and it bothered me. I was fine with it until this thread (thanks, Roger). But this got me motivated to fish out the cap that was on the car when I first bought it.
The cap was a problem when I got the car, as it didn't close tight and I had leaks. But I didn't know enough to realize what I was doing, so I replaced it then. When I went back to it now, I realize that it was an original Healey cap, and the only problem was that the metal closing tabs had bent slightly from years of removal. Also, the cap was crapped up with crud on the outside, making it unsightly. So, I tightened up the tabs, polished the crud off, and now I have the original back on looking brand new and fitting perfectly.
Anybody need a slightly used replacement cap? It looks kinda like the original. But not quite.
