Doesn't anybody even look at their rule book anymore? (I said "anybody", not "everybody".)
On the first page of the NHRA Stock class section is this:
"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."
This may mean that the OEM Challenger may be included in 2009, but specs and ratings need to be sorted out for those also.
