Okay, found the time to get off my butt and read some of the most recent bullettins getting about.

It's interesting to note that this now allows some of those things that have been complained about before (cars from Group 2 and Group 4, forest arches, FIA heads, 5-links in Escorts, etc), but is still toothless, in that it only allows for these vehicles in "Historic/Classic" rallies, Multi-Club/Club rallies (ala Dell) and piggyback to State/ARC events.
And really, if you wanted to, you could have written regs that allowed most of that before.
Still don't allow them within the scope of PRC, or within a State round. Only as part of a piggyback to the State round.
A step forward, but not as much as is wanted, or warranted, IMHO.
