Anyone who is willing to send me one of those non-working advance units would make it a lot easier for me to develop a possible modification to make use of a more readily available vacuum chamber. I don't necessarily need the clamp assembly that attaches to the distributor housing, just the advance chamber itself. PM me for a mailing address. Thanks!
