Box removal, best way to remove the bolts

[Steve Crum]

I'm going to pull the rusty box off my 87' GMC and replace it with the redone box off my 84' Chevy. I don't want to have to torch the 8 bolts on this like I had to on the 84' box. I've been soaking the nuts and lower end of the bolts every day or so with PB Blaster for the past week. I had hoped to have Bad Brad stand on the bolt heads while I hammered them from below with an IR Thundergun but it rained and BB sneaked back off to college. Anybody have any neat tricks to this, or are these just a ball buster any way you do it?

Well i had to grind the heads off of two because thay just turned in the bed floor and the rest come out with a bracker bar and wrench it was not hard to get them out. have you tryed to turn them yet?



p.s a sawzaw is handy to

I almost never waste my time, I fire up the blue wrench right off the bat!

my bolts turned too, so  i welded took the flat bar from a chain link fence and welded it between two of them and then they came right off with a breaker bar.

Steve, Something I've done is this: Get a big (3/4" or so) washer standing up or a short piece of pipe. Weld it to the top of the bolt. Insert a prybar through the hole, bucked up against the bedside to keep them from spinning. Cut if off, go to the next one. A little heat on the nut will help greatly also. Have fun with that!

Thanks for the suggestions, I guess I wasn't too clear on removing these. I would like to save these, but since I don't have anyone around to help I think I'll just cut them and replace them with chinese bolts from TSC.

If you have a welder, I have tack welded them to the floor to get them out.

^ That'll get the truck right off that bolt!

If you can reach the nuts with a die grinder, you can make  pie shaped cuts til a wedge is removed, then chisel the rest of the nut off. Careful grinding can save the bolt.
If you have a welder you might also weld a 3/4" nut to the top of the bolt head and remove the bolt with an impact gun while holding the bottom nut from turning.

I've done it by grinding a notch in the bolt head, as close to the bed floor as possible, tack welded the nut underneith, and used a chisel and hand sledge to spin the bolt..This only works after the bolt has spun in the hole and rounded the hole out.
