Bolt size- steering box bolts

Ok, so whats mod tech about steering box bolts? Well, I'm in the middle of a body swap and more on my 96 XJ. I'm transferring over my Durrango steering box and adding a bunch of goodies to it and I'm going to need new bolts as the stock ones will be too short, but I'm not sure how long. But heres the kicker- I will also be running:
HD Offroad front stiffeners
Dirtbound Offroad DIY front bumper
C-Rok Inner Steering Box Brace

So that would be quite a bit to juggle and mock up in place to try to get a measurement from (and I would be afraid of something slipping and killing my digital caliper when taking the measurement and trying to juggle it all).

If anyone is running a similar set up and could tell me about what length would be appropriate.

Thanks in advance

I'd not count on anyone's bolt length on here, and instead buy 3ea bolts 1/2" longer than stock and 1" longer than stock.

Its like an extra $1.72 at my local ace hardware for 3 bolts of that size.

Thow the other 3 (that you dont use) in your spare bolts box for whatever the next project is, along with the stock box bolts.

No digital calipers, no tape measures...

Stock is
7/16 course bolts 4 inches long.

so buy a few different lengths
