Drag Pac, Cobra Jet, and COPO are all inclusion cars (paragraph 3, section 10A), which are not "factory-production assembled, showroom available, and in the hands of the general public" (paragraph 2). That is why the 9" is not considered an OEM rearend for a Chrysler or GM, and therefore not a legal replacement .

Don't want a 9"...just saying by the rules it is fair game.
"OEM may apply for inclusion of any special production runs into
the Official NHRA Stock Car Classification Guide. Special run
must include a minimum of 50 units of an already accepted body
style, need not be showroom available. Applications evaluated on
an individual basis. Acceptance will not imply precedent."
Nowhere in that paragraph does it imply it is not a legal part. Once included in the Stock category it is the same as any other car in the family. NHRA is going to have to include more wording in the rulebook to convince me otherwise.
