This brings up an important issue for me. I have an assembly that I had done years ago. I can't for the life of me remember which flex plate I included when the machine work was done. I have the factory flex plate that was balanced with another project a long time ago, and I have an aftermarket internal, and an aftermarket external balance flex plate. The shop that did the work used to be reputable but work I had them do more recently led me to believe otherwise. Is there a safe way to go or do I take everything back to a shop? Sorry if I'm taking away from the OP.
