Rallye dash tach gauge lens question

I've been going back and forth on this for a while now and decided to see what some other folks thought about it. Here's the dilemma, the rallye gauge mask which has the gauge lenses attached uses the same lens for both the clock and the tach which has the small hole for the clock reset control. On the tach equipped versions, the there was a small plastic plug that was inserted in this hole since it is not used by the tach. I'm considering swapping a lens from another parts rallye dash which doesn't have the hole. Would you do the swap or keep the original factory configuration?

Swap in the new lens and find an unobtrusive LED to plug the hole and wire it up as an adjustable shift light.

NOTHING can't be improved upon...
