CPPA 440 A-body headers? Ever heard of them?

The Chrysler Power magazines should solve the mystery about the headers. CPPA was the publisher. As far as I know, both the magazine and the headers have been discontinued for 10 years at least. They pioneered the underchassis RB engine A-Body header, and were supposedly a pretty good part.

If you don't want the magazines, send them my way. A roof leak wiped out a pretty good sized stack of my old MoPerformance and Chrysler Power mags from the 80's and 90's.
