I have an extra 1.6l coil and 1.8l coil for sale, both in good condition. The 1.6l coil reads:

B61P
H4T00176

The 1.8l coil reads:

BPE8 18 10XB
DSC-501

I do believe it is from a 95-96 miata since it has 3 connections per coil.

Each coil is 30$ + actual USPS shipping from zip code 92647. Money order and paypal accepted.

 

Post pics. I know 94-97 (maybe higher) is a 4 wire.

There's the link regarding 3 and 4 wire coils, looks like late-95 to 97 are 3 wire. I'll get some pics up later on tonight.
