Wheel codes are the two digits on the outside of the rim next to the valve stem hole.
Should be JA or JC for '68. (one for drum, one for disc, but I don't remember which goes which way right now)
I used to be indecisive. Now I'm not sure.

I looked last night the two wheels I just refinished.
YOU MIGHT BE LOOKING AT THE WRONG CODES. Those look like later wheel codes next to the valve stem opening. The ones I have in that location are "HP" which is a Honeycomb wheel code.
The codes for your wheels may be stamped on the inside of the wheel on the backside of the front face. It is after the size of the wheel in inches. Mine say "15 x 7 JJ" which is a proper code for 15 x 7 rims with a 4.75 inch bolt pattern.

I thought I may at least use these for a while till I ran across some correct JC wheels however I have found out the 68 trim ring does not fit correctly with these wheels. The rim off sets are different and the inside trim ring edge does not set flush with the rim. It is about 1/2 - 1" off and looks terrible
I ended up having to find a set of JC wheels because these won't work.
Early 68 to about mid year only JC by the valve steam and the date is inside the rim where the tire seats. You can see that in some of my pics. Later 68 and 69 the date is next to the valve stem.
PS: anyone have info on these codes unfortunately this is all that I found under passenger seat. surprised it lasted that long being in the damp ole UK for 35yrs
HaroldB I just bought a set of rally II JC and on the inside of the rim is a D with a 1 or a 7 stamped inside the D no other date codes or anything do I have to take the tires off the find date codes Thanks in advance, Chris.H
Thanks Jimc2002. cant find anything about the D with 1 or 7 stamped in it and don't want to take tires off just yet . Wallace says the dates and other stampings are on the inside wondering if the inside means back of wheel or under the tire or they were made in late 67 and had no other stamping . I just hope I didn't pay good money for reproduction wheels..
My sept. 67 build 68 JC ralleys had the dates under the tire. There was a switch from them being on the outside surface of the rim to under the tire but I can't remember the cutoff dates.
That sounds right. I seem to remember the later JCs had smaller text size and additional markings. The 67 and 68 varieties had a simple larger text JC near the valve stem.
