Yes the AM antenna mast is elliptical. Just a note, I've seen original cars come with the tip lined and without a line. There was discussion that the replacement antennas did not have the line on the tip, but believe they came both ways. The attached pic shows 3 old antennas I collected over the years with plenty of patina. The middle one has the lined tip.

On AM you adjust the antenna height so that you tune the RF circuit. This helps optimize reception for the mixer-oscillator stage. Since the FM antenna is fixed height, you optimize/tune the am signal with a trimming pot on the radio itself. Usually there is a label noting "trimming pot" with an access hole located on the radio case.

Ride height is not a factor. If I remember correctly (my antenna theory occured 35+ years ago) the fixed height antenna is 1/4 wave configuration, 30 inches was chosen for best overall reception because its tuned for the midway point on the FM dial. If you shorten the antenna three inches it increase the sensitivity for stations on the low end of the dial, and if you lengthen it will 3 inches it will increase the sensitivity for station on the high end of scale. Not sure why your antenna is 23 inches.

Camaro Research Group Discussion / Originality / Re: 69 Z28 fuel pump

I know that this has been discussed before, but i would like to clarify the use of the 40987 fuel pump. I have one on my 57K 69 Z/28, which I thought was original. All of the info I have read states that the 40669 is the only correct pump. I have read several threads on CRG, but was wondering if any new info has surfaced since? Thanks for any info!! Bill
Bill, the only AC pumps I have found on survivor 69 Z's are 40669. The pump you have is dated the 57 day of 1971 and is therefore a replacement. In all first gen camaros and including 1970, the pump # was preceeded by two letters . The first letter represents the month and the second the year. For instance I have a pump on one of my june of 69 built Z's that is EI40669 which decodes to May of 1969. I believe in 1971 the first digit letter was replaced with the day of the year ,which is why your pump decoded as it did. The second letter/year decodes as follows: 67=G, 68= H, 69=I, 70 J & 71=K.

Thanks John! That's new information to me, and beneficial knowing that. I assume your explanation referred to the Norwood Fisher body plant? What about the paint on the front fenders, hood, valence, and other parts painted in the Norwood assembly plant?? Were those parts painted with an automated system? or manually painted? I'm curious because the 'inner' portions of my front fenders (the part inside the engine compartment) didn't seem to get full coverage; as if the painter sprayed from above and the under areas where there were contours, didn't get much paint... Is that typical of factory painted fenders on a '69 Camaro? Maybe Steve S. has some information on that as well from his survivor/original judging activity?
Hi Gary, Coverage on the inner (engine compartment side) of the front fenders is typically thin . There are many bends in that area and some area received very light dusting/overspray. In addition there are variations in color shades between the Fisher painted assembly and the Chevrolet front clip. Not always noticeaple, but it certainly was an issue. Look closely at original paint cars. The most noticeable example I know of was my 19k mile Tahoe Turquois 67 rs/ss L78. Beautiful original paint, but the front clip varied several shades from the doors back. Regarding Vintage Cerification (survivor) judging. Typically factory blemishes /anomalies (color variations ) are not deductions. Originality and preservation are the key criteria for our program.

I would be interested if a second edition is correct for my 06A. Just curious though why your 05A is a first edition and Edgmontvillage's 04C is a 3rd edition. A couple of weeks difference but backwards? Wondering if the books just go into a bin like situation and the line people just grab one. My 9B of 68 has first edition, my 4C has the second edition, and my 9A of 69 has third edition. my original 05A cars owners manuel is first edition. i may have a second edition stored somewhere if you need it.

..... Below is a picture of my 24k mile survivor and my orig interior 37K mile black rs/z.
Steve? Do both those cars have the optional console mounted 8 track players? *G* Wanna buy some old 8 track tapes? *G* Yes. Actually four of my cars came factory equipped with console 8tracks. Our twin orange rs/z has a factory 8 track as well as my white 14k mile rs/ss and believe it or not they all work. Thanks for the offer but I have plenty of tapes:)

I have several deluxe interior cars and all have black grab bars. One car, ivory houndstooth, orange houndstooth and blue comfort weave. Quite honestly its not something I've spent time researching, although I have many pictures of unrestored cars that we have certified through Vintage Certification program. At this point I will only provide firsthand examples and then based on the data make a opinion. Below is a picture of my 24k mile survivor and my orig interior 37K mile black rs/z.
