Default steering box bolts

For my gasser project I had to move the Vega box forward to a front steer configuration and this put the steering box mounting plate right behind (on the inside of the frame) the front spring perch, I could not get the bolts in unless I cut holes on the front spring mounts so I thought I'll drill the holes out in the box to get rid of the threads and weld a stud to the steering box mount, I figured I'd use grade 8 bolts, could I weld the grade 8 bolt with out screwing up the temper of the bolts????

It should be fine- there isnt enough load on the box to worry about.

I would gusset the back of the box mounting point and weld through a couple of sleeves so that you do not collapse the frame rails (there are reinforcing plates available precut for GM steering boxes on most 4x4 sites). They have learned that when you move things around or add different loads to the frame that it often folds under stress.

Welding the bolts will effect the temper of grade eight bolts but they are not in a lot of shear so it should not hurt. You use grade eight bolts to resist shearing motions, not to increase a claming load (increase the thread pitch if want to hold it tighter together with the same size bolt; going from course pitch to fine thread).

Dave,
this is what I have for a mount and how it is connected, I had to mount it within constraints of proper steering geometry I have thought of welding nuts in place of the spacers

I would weld that bad boy solid instead of tacking and try and think of a reinforcement to take some of the load to the out side of the tube (channel that would fit over the existing frame and weld in place to beef it up). There could be a lot of load placed on that area depending upon how you drive and the wall thickness of the tubing you used to resist it might not be up to the task (though I think you look stronger than stock now).

Dave,
the box mount is tacked until I get the rest of the front suspension squared then I'll weld it solid. The front rail are 2x3x.120 with a 2x2x.120 x member (you can seethe edge of it in the bottom pic.) and the spring mount sit on a 2x2x.120 "block". I'm still in a mock up figure out, scratch head, and bang head against the wall stage right now. I'm sure that the front end is much stronger than stock and will be more so when I get the cage installed with down bars to the frame.
