Hi Tom -
Those are actually not from 72 MY, those "Star Mag Style" steel wheels were the 73-76 base wheels on our 914s, as well as the special wheels used on Super Beetles of the day. They actually look better all silver as OE.
They should actually be painted all silver with black on the back, with a black plastic center cap - which you can see in well restored form in the O&H forum's Wheels & Tires nailed thread at the top, along with a bunch of the other OE wheels, as well as some aftermarket ones thrown in.
There were also a different silver painted steel 914 wheel for 70-72 MY - often with a baby moon sized hubcap (sometimes with chrome trim rings too), plus the Pedrini, Mahle & Fuchs 4-lug alloy wheels, the various flavors of 8-spoke Mini-Lite etc., Western wheels, & many more!
It all depends on what look you like, so also cruise 914 pix in google to see a variety (for any wheel choice, you'll want a 40ET offset though - not the VW offsets).
A common way we got the 5-spoke look without any hub adapters or mods, was the Riviera Alloys (they're on my 914 in the avatar).
Good Luck!
Tom
