Dana 20 rebuild, looking for bolts

Currently have my Dana 20 apart rebuilding it. I got the case cleaned and gave it a healthy coat of Rustoleum black. I was thinking that instead of cleaning up and painting the bolts, new ones might be in order. Google was no help. I also checked the usual sites, Wild Horses, Tom's, Duffs, North East Classic Ford Parts, and Bronco Graveyard to no avail. Does anyone know of a source of new bolts for the output shafts, cover, and retainers for a Dana 20? I could get the adjustable detents to cover that but a complete bolt kit would be sweet.

Thanks in advance,

Mike

I just took the bolts to local hardware store and found matches in grade 8 with coating. I think most were 1/2"-20, but don't quote me on that, been a few years since I rebuilt it. There is also a great article on here about how to seal it up well to make sure it doesn't leak when you're done. There are a few bolts on the inspection plate that go through the case, so you want to seal those up

See attached PDFs.
Ford MPC pages have typos on drawing, and some parts aren't listed on their parts list.
I think I have them all on bolt & washer list.
AMK Products Guide To Ford Fasteners will give more details on grade of bolts, or just buy all GR8.

EDIT: ADDED SHIFT ROD SPRING RETAINERT BOLTS TO D20 BOLTS & WASHERS PDF.

Thanks. The bolts for the detents seem to be exclusive. I didn't know if any of the others were or not.

I added them to the above PDF.

They are basically a 7/16-20 hex head bolt with 5/16" length.
I think JB Fab uses a set screw and flange nut to mimic them.

Type 1 in below photo.
