Stocker - Lifter and rocker arm problems

Hey guys,
I need some help finding some new parts. I bought a '78 LeBaron and inherited some valvetrain problems. I need to purchase some Sherman lifters and a new set of OE style shaft mounted adjustable rocker arms in a 1.50 ratio. Does anyone know where I could find Allan Sherman's phone number and who sells these rocker arms? Thank you very much.
