I am currently finishing up the fabrication of a front bumper for my XJ. The mounting of the bumper to the unibody will be similar to that shown in the following link.
http://jcroffroad.com/install_guides/XJFrontBumper.pdf
When I took the old bumper and mounting bracket off I snaped a 2 of the bolts off.
For the 2 bolts I snaped: should I drill and tap the bolt out so I can use the existing bolt that's welded to the inside of the unibody (this would require that I buy a tap - I'm a poor college kid)
OR try to punch the old nut out and use a new bolt and nut.
OR drill a new hole and use a new bolt / nut
Also my I planned on having the mounting plates welded to the bumper, Therefore I will be blocking the access to the inside of the unibody durring instal and will need a way to hold the nuts in place within the unibody. I was thinking of using some JB Weld to stick them in place. I dont care if they break once I begin to torque them down, just need to hold em in place till the threads are engaged. (plan to weld a 3" piece of scrap metal to the nut to serve as anti-rotation) Keep in mind that its pretty rusty and dirty in there and dont have a good way to clean it out. Any other ideas?? Or should I bolt the bumper to the mounting plates so I dont block my access while installing the plates? Now that I think of it, that would relieve stresses that would result from having variation in the braket spacing if it were welded directly to the bumper. (taken up by slop in the oversized holes)
Let me know what you think.... thanks in advance:rof:
