Broke steering box bolts

Ok so I pulled in to check the mail, got a little to far away. So I cut the wheel and here a loud braking sound. Lost all my steering. Get under the truck and at first I thought I'd broken the frame, but lucky it was just the bolts broke off. What's really scary is I only found 1. Idk when the other one broke off.
Anyone ever heard of this in a bone stock XJ? What's the best/newest steering box I can bolts straight on, from the junk yard?

it happens, even had it happen on my first stocker DD. easy fix.

-remove broken bolts from steering box tabs (heat and visegrips works wonders)
-go to hardware store of choice
-buy some Grade 8 bolts, 7/16" x 14 thread, bout 4" long
-also a good time to think about adding reinforcment plates

DONE!

Steering box is 20 years old, so I think now is a good time to upgrade.
