    On the shifter, do you happen to know when Frank Arone's car was built? His shifter is silver cad:

    For some reason I thought June 70, but am probably wrong.

    Lots of discussion on shifter finish in this thread:

    Still a bit of confusion about when the transition took place from CAD to phosphate. I'm about ready to do mine. Its painted currently. I will try to paint strip it to see. Its a late March-Early April build (TT is 04B).

    Frank's car is an 03E build...and the key to the finish changeover is when the shifter body was assembled. What is the date on your shifter? I just had my shifter restored by Pete this last Spring and the code starts "0300..." it was pretty clean and there was still a significant amount of silver cad present.

    Steve, Can you post info on how to read HURST Shifter Body 3138 Date Codes ???

    I have one of the last 1970 Z28's produced at Norwood 07E. My shifter
    body was Clear Zinc (Silver). Shifter is currently in pcs............

    Below Shifter Body is Stamped 0500411C

    Hi Chuck,

    There have been several threads discussing the stamped code representing a production date. Some agree, many don't. Pete told me my "0300.." code was March 1970 based on his years of research on factory Hurst shifters...The "3" represented March but I do not recall which "0" represented 1970.

    Pete Serio knows his stuff. I'd trust his analysis of dating especially since it is a Hurst convention for their shifters and not something done for Chevy or Pontiac or anybody else.

    Upon checking verified that mine too is a 0300 and it appears to be silver under the paint.

    My car is a 03C build date and has a Feb. dated Hurst shifter which is silver cad. What's odd to me is that Chuck's late built Z28 is also silver cad? Supposedly the change over to phosphate plating took place the last 2-3 months of 70 production. Maybe the changeover was later on LA vrs. NOR cars but I wouldn't think it would be that much!

    The link by Dave, (70lt1z28) in post #21, there's comments by member DCL70 (another Dave) who did a fair amount of research and determined the Hurst date coding. There are some other discussions on this topic going back 6-7 years ago.

    Scott - I know, that is odd that a shifter apparently dated May 1970...(with the "5" representing May)...would be silver cad. What I do recall about all of the discussions about the shifter dates is that there seemed to be some alignment of the stamped code to the car build dates, but many of the numbers/letter were never completely deciphered or understood.

    Yeah If the change over was in May then Chuck's shifter was made before the change over.. Guess I was concentrating more on build date of Chuck's car and not paying attention to the date of the shifter. It's odd there is over 2 months spread between shifter and build date of his car. Just goes to show you the variance on dated parts sometimes, not the norm but it does happen.
