7/16" studs is a common upgrade for a race car. I've got 7/16" studs all
around on my racer.
Sounds like someone replaced the hubs with 3/8" studs after they were
done racing, which I can confirm is the stock setup.
I'm wondering what you've done in replacing the axles, though. If the
prior ones were drilled for 7/16" studs and were used for racing, what
are the "new hard" axles you are replacing them with? If someone raced
with the prior set, it seems they should already have been the later,
harder axles. You can tell by looking at the splined end. If there is a
groove cut, then they are the later axles.
