89MJComanche Posted April 26, 2010 Share Posted April 26, 2010 Well, I went the to powder coaters today and picked up my JCR Offroad Rear Bumper. Damn does it look good!! I've been soaking my bumper bolts for 2 weeks with PB and Liquid Wrench. I did not get a single fu(king bolt out. I broke all of them. So now what? Drill and Tap? What is the threads for tap?? Or should I get JCR to make me a set of NUT CERT Strips to go inside the rails that line up with the 4 horizontal holes and the 2 verticle holes and use that instead?? Then I could just chisle off the old nuts welded to the frame and use the new nut certs with regular grade 8 bolts? Opinions?? Link to comment Share on other sites More sharing options...
jimoshel Posted April 27, 2010 Share Posted April 27, 2010 Your a better man than I am. I was only able to twist 5 off. The sixth came out. I would chisel, torch the old nuts off and make the nut certs instead. The trouble of drilling and removing the the stubs is just not worth it.

89MJComanche Posted April 28, 2010 Author Share Posted April 28, 2010 How do you suggest that I burn them off?? From the inside, or from the outside? It is gonna be kinda hard to get a torch all the way up in there right?? Link to comment Share on other sites More sharing options...
jimoshel Posted April 28, 2010 Share Posted April 28, 2010 There is straight torch tips, However the way I got mine out was to heat the bolt from the twisted off side and burn them out. With a small tip and steady hand you can burn the bolt out and not hurt the nut. After burning the bolt out wait for it to cool. See what kind off a mess is left. If it's bad run a drill bit thru it. if not then use a tap and clean the threads up. Go easy, don't rush it. Slag is harder than regular steel and you can break the tap off. I salvaged 4 nuts this way. The fifth was shot so I just burned it off and used a fender washer and nut to replace it. Link to comment Share on other sites More sharing options...
Darren Posted April 28, 2010 Share Posted April 28, 2010 I drilled all the holes out to 3/4" through the "frame" and used crush sleeves and 1/2" bolts. Link to comment Share on other sites More sharing options...
