Mark, you always new it was illegal in stock? Please tell me how you always new this. Explain to me where it says in the rule for replacing a rear with an aluminum center section is illegal. Below is the rule, point out were it says it is illegal.

REAR END

Original rear end may be replaced with another from the same
automobile manufacturer; truck rear end prohibited. Distance
between backing plates may not be changed. Any gear ratio that
fits third-member case or housing permitted. Limited-slip or
ratchet-type rear ends permitted. Reinforcement of spring perch
permitted. Spools permitted only with aftermarket axles.
Aftermarket axles not required for front-wheel-drive vehicles.
Larger brakes may be used. Replacement rear end may be
narrowed or widened to obtain original rear-end width. Bracing
or beefing up the rear-end housing permitted. Swing axle
differential may be replaced with conventional housing; stock
trailing arms must be retained, may be beefed up and adapted
to housing, must retain transverse spring. Must install Panhard bar.
Frame may be notched for driveshaft clearance. Distance between
OEM backing plates and OEM wheelbase must be maintained.
Coil-over shock or four-link adaptations prohibited.

See General Regulations 2:11.

Jeff, I think that argument is mute. According to NHRA is is not a performance advantage. Anyway I have data and you don't. As far as opening up a door to custom parts. First, it would have to be from the same manufacture. Second, you mean parts like aluminum cases that replace the cast iron cases on toploader's? Would you like me to run through the list of parts that are legal that will open up the door? The parts are not out sourced, Ford and Mopar offer aluminum center sections and they have for many years.

There is nothing stock about stock eliminator. Anyone who believes that is living in the past.
