I'm installing a front crossmember from an '84 in my '68. All I had to to was drill two holes and the thing lined right up.
The biggest pain was getting the old rusted bolts out of the '84. As you know, there are four bolts holding the crossmember to the outsides of the frame. They are behind where the upper A arms mount. The upper bolts are just big bolts. The bottom ones have nuts welded to the crossmember. Those welded nuts stripped when I was removed them. Yes, I used a RBFH. Question: Should I rethread those bolts to a bigger bolt size and turn a bolt into them OR can I just send a longer bolt right through the welded nut and tighten it with a nut on the other side? I'm just nervous about it being the front end. ![]()

If you through drill the welded nut and use the same size/grade of bolt, using a nut on the other side will be fine. I would make sure the welded nut is flat where the added nut will contact and I would suggest a thread locking compound be used.
Drilling and retapping will work if the welded nut is large enough for the larger size bolt needed. Jim |

You can try and torch the nut off if you have one if not then go ahead with your original plan you could allways tack tweld the 2 nuts together when done just dont tack it to the bolt.

i did this once too and i had tried to retap the nut and it wound up being a PITA your way of thinking about puttiung a second nut on is a good one but like the other guy said use thread lock and make sure its flush

How about an all-metal lock-nut?
