I can also say that he is a very straight up trusting guy to deal with. Myself and many forum members have purchased from him.
Thanks for the Kind words.
And , no offense taken relative to various perceptions of the practicality of rebuilding a pulley. I've done it myself, but I would not recommend it as a DIY. Setting the rivets takes correct tooling and observations of tolerances, etc And the springs should probably not be re-used (I have made heavier duty springs to use instead).
To the OP, depending on how long it ran like that you may have scoring on the input shaft of the SC to contend with. In the pic below, you can see how the clutch-pulley's backing plate wore in to the input shaft of this SL55 V8 supercharger .
Cheers,
