1  Camaro Research Group Discussion / Originality / Re: 1967 Jack base 08D car #000087 on: June 04, 2012, 10:02:58 PM
After researching Camaro jacks for many years I have found that the Camaros made in Van Nuys were issued jacks made by the the Walker Manufacturing Co. ("square" type post with date code stamped near the top of the post). Sometimes these jacks did not have the date code.

The Norwood Camaros were issued jacks made by the Universal Tool Co. ("keystone" type post stamped "UN" on the up-down lever and with date code on the rivet head). The date coding on these jacks started in "early" 1967, not the Fall of 1966.

I also have seen 67-69 Camaro "keystone" jacks made by "RH INC." but not that often with the date code near the bottom end of the post near the seam. These RH INC. "keystone" posts will NOT fit in a UN "keystone" base.

There is a lot about 70 Camaro jacks (both types) on the NastyZ28 website.

BowtieSweden,

The GM part number for the air cleaner assembly is 6484584 (69 Camaro & Chevy II w/350 4BC w/A.T.) as per my 1969 Corvair-Chevy II-Chevelle-Camaro Parts Catalog (Oct. 1968). The M.T. air cleaner is part number 6484583 for the same model. If you find one at a swap meet there should be a white sticker on the side of the base with the part number but most of the time this sticker is long gone. I have 3 original 1970 Camaro SS350 air cleaner assemblies (GM # 6485242) as well as an original 6485240 air cleaner (1970 Chevelle w/350 4BC), all have the white stickers with the part number.
Good luck searching.

I have been recently researching the correct spark plug wire LH rear SUPPORT for my 70 Camaro SS350 long term project and found that most 1970 Camaro models were issued the support (marked "#5" with the oval hole) on the far right on my photo below. The support (2nd from the right marked "1970" and "#4" with the round hole) is identical to one on an original 70 Z28 w/1,100 miles.

I believe the one marked "#3" is for a 69 Z28.

I have what I believe is a 69 AC fuel pump. It has what appears to be "HH40669" stamped on the mounting flange of the pump. Can anyone decode this?

I believe your "HH40669" AC fuel pump is dated August (the 1st "H") 1968 (the 2nd "H"). I have done a lot of research about AC fuel pumps during the last 20 years. It all started years ago when I found a 1966 Chevrolet 327 engine ("T0521HAR", May 21, 1966 with roch. 4bbl.) in a junk yard which had all of it's original components (carb, starter, distributor, fuel pump, etc.) according to the stamped part numbers and date codes.  I decoded the "4657EF" fuel pump to be May ("E") 1966 ("F").
My fuel pump date code theory is as follows:
The first letter is the month, A=Jan, "B"=Feb. ...........................L=Dec. (the letter "I" was used).
The second letter is the year, E=1965, F=1966, G=1967, H=1969.
NOTE: The AC pumps made in 1964 and prior do not have the 2 letter. I have an AC pump stamped only "4657" from a 1964.
Sometime in the early 1970's the date code changed to 3 numbers (the day of the year) and one letter (the year). I am still working ion this code.
