64-72 Shifter Knobs

[Mark D.]

Regarding 64-72 (and probably beyond) shifter knobs, are they being judged for configuration during Flight? Has anybody had any experience with loosing points on a reproduction?

I ask because, the base of the reproduction units vary significantly from original. Where the originals had a radius edge along the opening on the bottom, the reproductions have a very sharp edge. A judge would only need to run his/her finger along the opening to immediately detect the difference.

Anyway, just wondering how they are being judged.

Well, do not know about that radius however judges do check the entire assembly for correctness. Did take a small deduct for not having a small hole just below Knob on shaft (not sure what was meant by that) just showing they do check.

Nothing to do with a shifter knob but do you remember this photo of this motley crew.

I'll bet Reggie never thought he would be Ralph Kramden's secretary.

As you can see, the difference is easily detectable...

Was there a 1st and 2nd design shift ball for early 64? I thought there was a change in the construction. If so, does anyone know what the change was? I don't have my 64 AIM handy.

A few changes to assembly, as for just the knob that's still a ? Also see a number of NPC marked.

Re: 64-72 Shifter Knobs

I think I remember reading in an old Chevrolet Service News or bulletin that the early 64 knobs would strip their threads if tightened too much. I think an interim fix was a threaded brass insert. Later knobs were all metal? Maybe early knobs were plastic? I'm a C3 guy so this stuff didn't really sink in when I read it many years ago.

Piper, judge 63s and you won't have to worry about it.

TSB #691 Dated September 8, 1964 was reprinted in he Summer 1979 Restorer. Attached is the page from that TSB that deal with 1964 shift knob thread damage and early / late shift knobs.

Re: 64-72 Shifter Knobs

It looks like the 2nd design 64 knob, going forward, were copper coated black bakelite...

Re: 64-72 Shifter Knobs

Mark, that has been my experience too.
I tried buffing a shifter knob long ago (70s) and it quickly breaks through the chrome and brass layer exposing the black plastic center.
They are as heavy as iron but the core is plastic/bakelite. Bob

You have taught yet another lesson. Brass, not copper.

May the rust be with you.
