Mine have some part numbers that I couldn’t find searching the web.

Ring gear part numberr:

SA IH H1815

Pinion:

53810


Ring gear diameter is 12.25 and has 38 teeth and pinion has 7. Math comes out to 5.4287, rounded up is 5.43.

I’ve found that searching for EatonH110 doesn’t come up with much. Searching for GM H110 seems to have a few more results. Mine were listed on EBay as GM H110 gears. Seller is a machine shop with great ratings and reviews.
