What threads did it end up being? And what gpm did you end up going with?
I believe the inter bolts were 5/16 (24 thread count or TPI or whatever) and the outer were 3/8. Used 1 1/4 with a washer and worked great. 5gpm Udor. Mike Hansen at Dultmier was great to work with. Pump and gearbox for $720

Nice!
Looks great. I believe those red caps need to be replaced with breather caps?
Those are the replacement caps…they shipped with temporary caps
You might want to make sure the 3/8 are not 7/16. On my engine, 3/8 would fit but felt a little loose. 7/16 coarse was a snug fit.

The proper bolts were included on my gear drive from envirospec.

Enviropspec has great customer service. Call them and they will help you with anything.
Well, the vented caps are usually yellow so might want to compare the red shipping plugs to those you installed.
