Roger, good work. I should have known to check in the MPC, I knew Accessory Packages are listed in the '66 MPC.
I gather you didn't spot the 988817 Package that Eric White shows in his book for the '70 GTO (and I assume A body in general). Curious if it is a valid p/n.
For anybody that didn't see it, here is the 988834 kit on eBay.

I assume the 988994 kit was related to the unique '71 GTO bumper? While the 988993 was specified for all other A body models?
No idea if the 988994 was superseded by the 988993 kit or simply obsoleted without an available substitute. Would be interesting to compare those 2 kits side by side.
But if the 988993 kit works on a '72 GTO, hard to imagine it wouldn't work on a '71 GTO. Unless there were differences between the 2 years? Or if perhaps Eric White listed the wrong kit for '72 in his book?
I checked the Accessory brochures in the GTO Source Book. Shows a pic for '70 with the pull handle, describes both the '71 and '72 (no pic) as having a pull handle.
That suggests the kits for those GTOs were more like the 988834 rather than the "slide control" seen on the 988993. Unfortunately, the brochure only says they were available from the Dealer, doesn't provide the Package p/n.
I didn't pay close attention, but the brochure indicated that the Inside Hood Release was standard equipment on big Pontiacs starting in '71 and available on all other Models as a Dealer Accessory (big GM models had a major redesign for '71).
Given the outside pull handle hood release used on the '73 Firebird, I always thought it would have been a relative no brainer to modify it into an Inside Hood Release.
