Woking on my 70 Barracuda. Going trough all the bolts to retorque after putting 500 miles on her, Has anyone modified the K frame bolts? I cannot tighten the front two to 145 foot pounds as it seems the nuts inside the frame rail are turning, Almost feels like the bolt is ready to snap but I am sure it is the nut breaking loose inside the frame rail. I am afraid to torque any more as it could snap something,

Any suggestions?
 
Most likely the spot welds on the nuts inside the frame rail have broken loose. Are you a decent welder? You can drill holes in the frame rail right next to the captured nuts and re-weld them. And then weld up the holes.
Additionally, if you have over 100 FT-LBS torque now, I seriously doubt they're going anywhere.

Thanks ex Cuda over my problem is the frame rails are completely painted and detail just like the rest of the car. Was hopeful I wouldn’t have to cut into them in patch and paint. Do you know if anybody’s put a bolt all the way through the frame rail?
 
You could run a trough bolt I guess, but you'd have to add a tube (welded) to keep from squishing the frame rails. Be better to a few holes underneath to weld the nut back and then grind smooth and repaint. The cross member (K-Frame) will cover most if not all of your repair.

Well since I have the QA1 setup the blue circle shows where the front bolt goes, not much coverage on the frame rail.
