I've been looking periodically without any luck for the alum 3-groove pulley made as part of an OBA kit made a few years back for a York comp. I haven't been able to get just the pulley as I don't need the bracket since I will fab up my own for a Sanden compressor. A friend has now offered to get a pulley machined for me, but I need dimensions, and I would like to avoid removing mine. So if anyone has the drawing or dimensions that wouldn't mind providing them, it would be much appreciated.
