The AMC over the counter modification parts were not accepted until just recently by someone. That means it must have been turned down by the tech dept in the late 60's and has been denied for several decades.
In recent years several non-stock, bolt-on, across the counter modification parts that are only listed in OEM accessory catalogs have been added which is in direct contridiction to the rulebook. Maybe whoever is accepting this stuff needs to be reminded of what their own rulebook states for Stock class!
"Section 10A, page 3 ENGINE: Must be same make and year as car used, aftermarket NHRA-accepted cylinder blocks permitted. Equipment other than original factory-installed prohibited. Any special equipment export-kit (superchargers, dealer-installed options, etc.) automatically disqualifies car."
Wanna bet that rule gets deleted for next year?
Maybe it will be changed to..."Across the counter parts listed in accessory catalogs by the OEM for bolt-on modifications will now be accepted no matter how long ago the catalog was printed or how many times the original tech dept turned the parts down."

Like Dwydendorf commented; the rules seems to have preference on certain car makes and are not applied consistently across the board.
Let's take an example as to "Dealer Installed Options"; how did the Saleen and Roush cars got in the books?
There are so many items such as options and modified parts that have been allowed in the books and suddenly everyone is up on arms and get their shorts all wadded up when AMC's get some allowances like other makes!
We can all point to how many things NHRA has allowed throughout the years. Another example is when they allowed automatic transmissions in the 1967 Galaxie 427 with two 4BBL's; they were a stick car only from the factory. When I asked NHRA about it, they said since an automatic trans was available in the Galaxie model, they allowed it although it was not available with the engine.
Another example was many years ago when a friend was thinking of running Stock Eliminator with a 396/375 HP Chevy. He buys a set of OEM pistons and also the replacement TRW pistons. Purchases the latest Lunati stocker cam and calls me because all his valves were hitting the piston dome. I check the engine and there was no way the cam would clear the pistons. I make a few calls and find out about the machining and massaging of the valve reliefs and later on the glass beading to hide the mods to make the cam work. He choose to just bracket race in lieu of modifying his pistons. Therefore, could we assume the pistons were modified prior to submission to NHRA for approval?
..and the list goes on...
