Again, I would remind you Kenth that Pontiac Master Parts books & charts listed in Pontiac Service manuals often printed months before the beginning of production have considerable limitations. Quoting them versus actual hands on experience brings a LOT of errors into the mix.

The actual usage of the KU stamped 14x6 Pontiac Rally II was.

-1971 Production A-body's AND Venturas beginning typically in Dec of '70 after the supply of JT's was exhausted.
Of note, a few A-body assembly plants like Lakewood GA & Oshawa did not resume production until later in late Jan of '71. This delayed the usage of the KU rally II wheels at those plants. With the production down time during the Strike, Pontiac Engineering was still hard at work, & the combined use KU coded 14x6 Rally II was only one of quite a few revisions that made it onto later '71 Pontiacs.


As far as '72 Venturas go, I've only pulled KU coded Rally II's off a few very early production '72 Venturas. Would think I would have ran across many later dated examples if they were used much later in '72 production.

For decades I've sought out '72 Venturas when buying partscars & boneyarding for over a dozen specialty core parts. In building up 8.5 X-body rears, the '72 Nova & Ventura rearend housing is a one year mono leaf housing. As such I've pulled a TON of original wheels off '72's.

For '73 model Pontiac A-body's & X-body's, the HN coded 14x6 Rally II was introduced.
These were also used on '74 models. The 14x6 HN Rally IIs & their replacement, the HL's, have never been a Rally II wheel that I've actively sought out, but with tons of wheels coming through here, I've ended up with more than a few.
