    Yes, that's what I found odd Moper. While I have seen small balancing tabs on converters, I've never seen the number and size of weights that the old TC has on it. Guess we'll know once I get the Duster back together. I'll be sure to post the follow-up results here .....good or bad. Be well Pat

    Beginners,doing multiple modifications at once......
