I think they came with 3.07 in 84'.
Most will tell you not to get 3,73, but I will pm you a video of an 84 with 3.73 gears, and at higher rpm range you decide if you think they are too much. The guy is usually on another forum I think, so you could even contact him.

How do you want to drive?
Are you worried about fuel economy?
Do you have any engine mods ?

It depends on where your engine makes its power. I have an updated 350 with a tunnel ram running 2 340 Holley carbs. I don't start to make power until it hits 2800 rpm. So 3.75 gears do work well for me.

When I had to replace the diff in mine, I went back to 3:07s. My 84 is stock with some bolt-ons. Not to mention I just drive mine, I don't race it.
