I had to get two replacement Eagle H beams to make a set again. I gave them the numbers off the weight card but the rods I got were 10 grams heavier on the big end than the old ones. I bought these things about 12 years ago so returning them wasn't an option and if you've ever seen these rods you know you really can't take anyweight off them. My machinist suggested to just add the 10 grams to the bob weight on one journal and install those two rods on the same journal. He says he's done it before without a problem and everything balances OK. So that's what I did.
