stock class rear axle?
 
I am considering stock class racing my 56 Chevy, [again] after many years. does the rule book still say you have to run a corporate rear axle? I do ,not want a 12 bolt.

can I use a '55-'64 style center with different bearing ends and race axles? also can the tubes be shortened[just a little]?
thanks Rod min AZ

Yes and No

Rod, you could use a 57 -64 Pontiac/ Olds rearend housing if you wanted to retain the stock look. It is not legal to make the stock rearend narrower plus the tires will be up against the springs if you do. A cheaper alternative is finding a 8.5 out of a Camaro or Firebird. Just as strong as a 12 bolt, but not as many ratio options.

Better reconsider the 12 bolt ,with Pro gears, if it's going to be a stick car.

Pontiac/ Olds not legal in Stock

The Olds/Pontiac rear is not acceptable for a Stocker trifive......I asked.

REAR END Original rear end may be replaced with another from the same automobile manufacturer; truck rear end prohibited. Aluminum center section permitted only on vehicles that were originally equipped with same. 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.

So a COPO comes with a 9" Ford so I guess a 9" Ford is now legal?

What Jim said. Tech Director said, must be Chevrolet.
And a big no on the 9". Asked about that one last year.
