I'm thinking one of those old 70s - 80's aluminum topper. Very cheap, light, and would prove the point one way or the other. If it weighed 60 lbs and I still dropped a 1/2 tenth, then... Put it on with C-clamps, make a pass, remove it, make another pass. Should be a tale-tale
However wide your bed is 5 and 1/2 ft or so?.. get two of those by 4 ft and they could lay down in the back of the bed and then put them on and turn them sideways..
Speaking of sideways....lol...
Wouldn't the torque of a stroker kit push you through all this trouble? LOL....
