AZ wheel date codes for dummies

[Kevin G.]

I'm the dummy! Can someone please help decode these wheels?

1. K 1 6 11 stem 16AZ
2. K 1 7 8 stem 22AZ
3. K 1 95 9 stem 8 AZ
4. K 1 3 9 stem 20AZ

K= Kelsey
1= Chevrolet
next ?(6,7,95,3)
11,8,9,9= month
16,22,8,20=day
AZ= 70-72? 15x8 Corvette wheel

TIA,

Kevin

Re: AZ wheel date codes for dummies

Kevin...think it works like this:

K = Kelsey Hayes (manufacturer)
1 = Kelsey plant #
1 or 2 digit stamp = year

(valve stem hole)

1 or 2 digit stamp = day

AZ = type/size (AZ is 15" dia. X 8" wide)

your numbers as follows:
(19)76 Nov 16th
(19)77 Aug 22nd
(19)95 Sep 8th
(19)73 Sep 20th

Thanks Don! It was the (95) that I couldn't understand. The AZ's were used for what years?

Re: AZ wheel date codes for dummies

Yeah, think they stamped the '95s with the 2 digit code to dicern between '75s, '85s (don't know if 85s were stamped with 1 or 2 digit code) and '95s.

Where are you in the DE valley? I grew up in Wilmington.

These wheels sound like they will be perfect for my driver 72!

I'm about two hours north of Wilmington, in Buckingham, Bucks County. We do have several members from DE!

Thanks again Don,

YS= 69-70 Chevrolet "B" body w/disc brakes, replaces "DC",
15x6 JK, .06 offset.

YW=69-70 Chevelle Pass Rally w/DB, replaces "XB", 14x6 JJ, .88 offset.

That can't be right? - they are all 15" wheels.
I suspect they are later then 1970 wheels.
one pair is 15X7 - the other pair is 15X8

Kevin -

The "AZ" 15x8 rally wheel was the standard wheel on Corvettes from 1969-1982.

Then I suspect his info may be incorrect. As far as my references go, the only 15x8 rallys through 75 were AZ's. He says the YS wheels are 15x7 and my references say 15x6. I don't see a Y in the pic of the "YW" wheel and I would suspect it may be an FW which is a 15x7 not 15x8. JMHO, who knows?

Re: AZ wheel date codes for dummies

Yes - took a closer look FW

one pair is 15x7, the other is 15x6.
Thanks
