It's my understanding Jr sold the business.
See this thread from the Corvette world on how to take the guts from a Wells VR-715 ($35 at AutoZone) and install them in the original Delco VR case.

I would go with the VR-715 guts. It's all surface mounted devices vs. the capacitor on the kit version which is through hole.
