Rear suspension too stiff

It would only take 10 minutes to re-torque those bolts and it doesn't cost anything. May as well try it.

The ride on my '67 Barracuda is awfully stiff (the same as 68original described). So I guess I'll try that torque technique RustyRatRod suggested. - But it still doesn't make sense to me. I need to finish up my rear brakes this weekend after parts arrive. I'll post back in a few days to let you know if the ride improved.
