That's an excellent question Barry.Talk about old age, I didn't occur to me to check.I just got the rods today and was reading the specs on the box and tossed a whole rod on the scale and it was 934 grams and my mind was , where did the extra 100 grams come from. I was just curious if this was a moot question and there was a quick answer like , they don't weight them with the rod bolts or something. I will break out the fixture tomorrow and see what it says. Thanks for the response.
