I am pretty sure they came out around that time or a little earlier. The first 16x10's were drag race only wheels and they made them 2 piece to make the tire change easier at the track. See ya JOKER JASON. Dick Beith was the guy who started the comapny.
I believe I have an old '65 Hot Rod mag with an add for the two piece wheels..........................
The earliest ads I can recall in my old magazines is (I think) 1967. In fact, the first ET-III's used a fastener on either side of the spoke (much like an American 200S daisy) to hold the wheel together. I don't think that version lasted very long before they went to the single Allen screw in the center of the spoke. Mark
I have an original set of 2 piece 16 by 10 ET 111's with the "unilugs". I seem to recall 2 ads in 1969. One was Don Prudhomme and the other Shirley Muldowny. I recall the year of the ad because I have them on my 1967 AA/FA, and they are not correct for 1967, but being aluminum instead of Magnesium, they are easier to maintain than my more correct Halibrands.

I owned a pair but sold them to a guy restoring a twin engine FED. These things were extremely light! Very thin in the hub area also.
The earliest ad I could find was in Hot Rod, July 68. Note the fasteners on either side of the spoke, rather than in the center.
They were like that when I found them. I honestly think it was gold paint. I think someone said they actually were sold new with paint on them.
The ET Supers were available with a "gold tone" finish on the spokes. I'm guessing that the ET III's were, too.
