I wonder if even your local tech director would even know....

When I asked Jim Anderson about running a 2 piece driveshaft, he had to call Pomona because he and I both thought it was illegial, but no mention at all in the RB...Pomona said it was legal, so I did it. Just means I have 4 DS loops instead of 2. It allowed me to go to a driveshaft with a higher critical speed given the extreme length of a XC truck.

This may be same issue...get clarification on the rule...Maybe no dually/FF rear ends? As raised above, depending on how the RB is written, would that mean that the stock trucks couldn't even use a truck axle, or just not cars? IMO using a 3.25 truck axle would be stronger (equals safer) than a 3"...granted that's pretty big already.

Definitely ask your division director, and when in doubt, have them ask Pomona.
