That figures. Any way they can save a buck. Unfortunately I don't know where to decode newer stuff, only 86 on back. I imagine a dealer could do it. I believe A&A and Cope Racing Trans. (and probably more places that deal with high perf. torqueflite parts) sells a 16 sprague "ultimate sprague" as they call it. I haven't used one but think it's a drop in. Thanks for the info.
