Valve stems for Rally Wheels

[JohnSSL78]

What is the correct length for the valve stems on the 69 Rally wheels? Did they originally use the DILL caps in 69 and what is the correct number on these?

Don't recall the length offhand, but they had "Dill 627" caps with the little "tit" on the end (the same valve stems and caps are still used today on GM and Chrysler products).

Reviving an old thread relating to a question about assembly line correct valve stems and CAPS.  Are either of these examples (#1 or #2) assembly line correct for a '69 Z?  As shown in the photos, #1 has fine ridges that extend onto the crown of the cap, a less pronounced tip and proud base.  #2 is a more commonly seen style with the Dill name in capital letters moulded into the crown, wider, further spaced, flatter ridges and a taller tip with a concave center and a level base rim.

627 cap is seen here, still around as JohnZ said.  Looks like your #2 I believe.

Cap #1 is the factory assembly line original. Cap #2 is your every day seen cap.

Hmmm?

In late 60's NCRS Corvette Flight Judging, the Dill 627 cap with the coarse ribs and the "tit" with the indentation is considered correct; the one with the finer/longer ribs may be from a later era.

Thanks for clarifying John.

I had a May of 69 ralley wheel with the original spare on it.  Spare had been on the ground once.  Had a dill 627 cap on it.

The Dill might be considered correct only because they don't have the originals or know what they look like. Cap #1 is CORRECT!

I have a set of 4 on Ebay....Reserve $200.00

You may be 100% correct but JohnZ is also correct with the info he communicated. From my limited experience with original caps I have not noticed your example but have a few of John's examples.
This cap came off a 68 DF wheel with a Jan/68 dated wide tread Goodyear tire.


This cap came off an original 69 SS Camaro Oct69 built car with the original tire and the cut valve stem/cap combo came off a 12/67 dated DF wheel. Both caps seem to be examples of what JohnZ posted. Additionally, NCRS is a great source of well documented and accurate info!

Chick,
When you get a chance look at the original YH spare that Skip was selling. It has my style of cap. Maybe Steve Shauger can chime in, I'm sure he knows since he  judges original cars and possibly has come across this before.

Yep, will check out Skip's original wheel valve stem cap. Also, pulled an original 68 corvette wheel and tire, and the cap seems to be the same as #1 listed above, the ones you have.  It's seen better days (chewed up on the end) but it does seem to match.

The spare tire on my norwood built 67 rs/ss 350 03B  when I purchased had 37k original miles. Tire appears to have never been used date code YUO1360
has the cap with schrader on it just like above.
