Anyone tried one of these HEI Distributors?

I called skipwhite and the guy who answered pulled a distributor off the shelf. He said that the picture in the eBay ad was not correct and that the distributor comes with a mopar style female cap.

That would make it appear identical to the this ProComp unit.

He also told me that to recurve the centrifugal advance requires springs and weights which they do not sell. I see that Procomp has a set and I bet they would work.

I orderd the distributor from skipwhite. Now need to order a coil.
