Just luck Rob. She helped me unload it after I had the gear change done, and while it was on the ground, I asked her to eyeball the diff cover and if she ever saw one for sale, let me know. She used to market marine Kohler / Briggs & Stratton engines, transmissions, and other mechanical stuff in the Philippines and other countries for an American supplier, and is very sharp mechanically.
I make my own tags from 1/8" thick brass flat stock and have an antique alpha/numeric stamping set (courtesy of the USN) and just hammer the data on the tag I fab. This one says TracLok 4.10. The tag is permanent and locked between diff cover two bolt holes. Also xxx'ed out the axle tube Dana p/n and changed it from 3.55 to 4.10. :cheers:
