Okay, good, I was thinking the J-style hump started in mid-66, but it was
mid-67. I looked at the parts book and this change isn't documented. I may
have a couple of the early non-hump 4-bolt wheels, but I don't know why
anyone would want those.
The change to the small valve stem IS documented: That started at the
beginning of '69, but you have to look at the listing for the valve stem, not the
wheel. Oddly, it looks like the first 10,000 cars got a small valve stem, after
that, thru '68, they came with the large stems. Apparently only small hole
wheels were supplied after some point, and it appears that there was no
change in wheel part number when that happened.
The parts book actually lists 4 different wheels, all 4.5" wide and all with the
J-hump. So the J-hump was supplied as replacements for wide-5 wheels,
too. Anyone have any of those?
The last of the 4 wheels listed is a special for M263 cars only (Squarebacks
with the Z-bar, starting in '67.) I have no idea what that is/was, although I
must have some. It makes me wonder if it is a stronger version that used
thicker metal. I would have to weigh some to see if I can see a difference.

I'm not familiar with Progressive Refinements. I'd love to see a copy, or
perhaps you could scan it. Oops, I see it's already scanned on thesamba.
I have a copy of something for Beetles from the early '60s that I think they
called "What Year Is It?" But that just calls out things that are pretty obvious
and external. Made for public consumption and not nearly as detailed as
Progressive refinements.
I have an early Robert Bentley manual for Type 3s (VW
Fastback/Squareback Handbook by John Fitzgerald) published in 1970 that
has a list of changes for Type 3s that I always wondered how they came up
with that info. Maybe they got it from Progressive Refinements. The latest
changes mentioned are in early '68.
