Measuring for a driveshaft, I thought I better put some weight on the frame just in case, so I loaded a dozen 50 lb. bags in the sweltering heat of Noon & no breeze, half-way through thinking "I'm too old for this *&%".
Good thing I added the weight...........Just kidding, I measured before and after, the weight didn't change a thing
At least I had an excuse to torque the leaf springs.
