Front Crossmember Bolts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

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.

Past: '05 Sierra 4x4 - Had 270,000 KM and running well when it was written-off by a stop sign runner. '94 F-150 from the "F word" company. I'll admit it...good truck. Sold what was left of it for $800 to a guy who came to pick it up at 11:00 PM with cash in hand. Hmm. '79 Sierra Grande (Black) organ donor - perfect rebuildable 4-bolt 350 and a good TH350. '76 Sierra Grande (Orange) - hate isn't too strong a word. Kid who bought it turned it into a hot rod. '68 C-10 R.I.P. - Dad's old truck...too far gone to resurrect. '59 C-50 - with hoist. Truck is gone, wife isn't. Nuff said.
