81 1000J Gauges

I'm looking for NOS tach and speedo for my restored J,but need to sell an NOS tach I purchased but isn't correct for my model.I'm wondering if anyone out there might know the model it's for.The headlamp out indicator isn't white with HEADLAMP lettering on it like an 81-82 tach and doesn't have an extra pigtail out of the wiring harness,other than that it's the same,may fit an LTD or other model I'm not sure.It's electronic as well,not cable driven.
Thanks for any input.
