Don't know if this thread // link, may help further, in shedding some light on things around that time with the HK's, seems a lot was happening with GM sourcing carburettors via ""Rochester Quadrajet"", with body dating and bodies at the time.... some others being soured via ""Cater Quadrajets""to suit the US GM market place during the late 60's... early 70's.

7028213 = 68 Camaro and 68 Impala 327 Manual only .
7028213 Was never used on HK Monaros, even though technically it would have been the next number in line number wise if Holden would have not have used the "8" designated "Monaro Only " Issue Quadrajet Carbies on the Type 2 Cars . I have seen a few early Type 2 Cars with the 7027213 DZ Carby also .
7028213 is the same spec carbie and next best option really to a real one . Be careful also many of the 7028213 carbies are "later issued" and "Carter made" Quadrajets with 1970s dates and different bodies . Will work fine but are much less desirable value wise.
7027213 DZ can be gotten in the US but it has the aluminium Date tag and uses the 1967 body , and are actually not that great of a carby for multiple reasons (1968 were better) .
The US spec Carby is not the same as the "Monaro only " Issue 7027213 which is a 1967 Dated Carby with an Early 1968 Body , as we must have ordered the 1967 Spec Carby late in the piece and they used the current issue 1968 Body at Rochester.
Hope this helps
