The part I like is when the weight limit is 100lb and the part being delivered is 95 pounds. I can lift 100lb pretty easy, while I’m looking at a box van full of 3-30 pound packages. A sub is heavy, but fragile? It’s a SUB. :-)
I was helping out a buddy install a diesel engine for the tractor pulls. We use a pair of OHM subs to set the front tires on and strapped the tires to them. I don’t know what it weighed but an 8-V 92 with an Allison automatic is 3 tons or close. Those subs were "fragile" LOL Kinda like Mike Tyson fragile.
I looked at the subs after we were done. They never stopped playing for one and there were a couple hundred small stones embedded in the bottoms of the boxes. He just laughed an said "it added character". You could see he had done it a few times.
That was one neat 49 Studebaker Pick up..
