Howdy! So I have three missing bolts from my 89 Pickup and I was wondering if anyone knew there size, pitch and what not so I can replace them. I tried the dealership but they couldn't figure it out so I'm gunna go to a bolt store in town but to do so I obviously need to know what to get. The bolts hold the back of my front diff. up. There are two on top (red) and one that goes into the side (green). Any and all help is greatly appreciated.

What that is is a diff drop lift, and the bolts to the top are on the other end of the mounting bracket. Those should be the same size as the one on the side of the diff.
Remove the bolts from the top, replace with grade 8 hardware, and find a matching bolt from a pick and pull to fit the side.
