stock elimator rear axle?

[Wade Mahaffey]

I would like to add to this thread an experience I had. I am building a 60 Corvette and was looking to go (Stock) racing. When it came to the rear, I wanted to use a 12 bolt for different reasons. Everyone (friends, racers, NHRA tech personel) said, no problem go ahead an use it. Everyone except Wesley Roberson NHRA Div 4 tech. The rule book said the replacement rear must be the same "type" from the same corporate family. The word "type" meant spicer (rear loading) or 3rd member (front loading). So you could not use a 12 bolt in the 53-62 Corvette (Wesley). After doing some investigation of my own, I found many violations to the rule book on rears. Including a few direct violations setting on world records, and not just Chevys. I gave no information on the cars and/or names. I did go a few rounds with Mr Bruce Bachelder at NHRA. In the end the 2010 rule book was ammended and the word "type" is no longer there. Now it's just a rear from the same family. So you guys with the 55's can go ahead with the 12 bolt "and be legal" now. After all that mess, could'nt get a 9 inch tire on the Corvette anyway.....so I went to a 10.5 and had to move it to S/S....there were several other issues on the car that made it more favorable to go S/S.
