I’m leaning toward 69 date coded wheels that I will have re-chromed.

Be careful with the re-chroming. If the wheels getting the re-chrome have pits in them chances are you are not going to be happy with the outcome. You really have to have a good set to start with. Peeling chrome is OK.

This discussion about the 15x4’s and difference in the first style and second style of the original wheels was on the site here about a years or so ago with good pics showing the two wheels. I have the second style 15x4’s on my car now. When I bought them they were okay driver quality. I searched for ever before finding a chrome shop that would replate them.
I’d post pics here but it would be easier for me to find the cure for the common cold than figure out how to post a pic! I’ve got a lot of money in mine so if you can find a nice set for 6 or 7 hundred you better get em.

Thanks for the reply, I agree the core wheel has to be a pit free clean original.

Bill knows all about this as he found a company in California that re-plated a set of wheels for him. I don't believe this service comes with a guarantee that the castings won't break when they are separated for plating if I recall correctly?

I’m going with a shop that will plate the wheel together
I like this process better it might not produce as durable a finish in the space between the center section and rim
But I feel more comfortable with this method as the car will be raced.
I think one could lower the risk of the chrome failing in this area by sealing this space with a clear type of sealer or clear coat paint

Can't be done ... center section is aluminum and outer rim is steel of course.

How was the aluminum center attached to the steel wheel?

Aluminum cores are pressed into outer steel hoop then welded in with (5 ea) 2" beads between 2 dissimilar metals as seen here on the back side of this NOS rim. Welds need to be broken to separate the hoop and then both pieces would need chemical stripping before being re-plated in this process. Expensive and I was told there are only a couple who will do this work now days. I was also told that if the aluminum core break or cracks when being removed from the outer hoop, the wheel is garbage.

It is not 2 dissimilar metals. You cannot weld aluminum to steel. There is a steel tab molded inside the end of each aluminum 5 spoke or I should say the aluminum is poured-molded around the steel tab leaving a portion of the steel tab sticking out at each end of the spoke-that portionof the steel tab is welded to the rim.
