As noted, I have changed lots of lowers, but as a rule the uppers last a lot longer. If you feel like you want new ones, then use the Heratbeat ball joints, they are close enough for what you are doing IMO.
 BTW riveting them in is not that hard, if you don't want to tackle it, take them to a big rig truck shop, they will have a rivit press and the tools.

I have never seen the white 70 switch on 69, A friend has a 11B/69 and it has the metal switch like below.

It is Important to note - That Canadian Delivered Cars used a different manual, they had a Red Front Cover instead of Blue, and they dont contain the Helm pages.

65  Camaro Research Group Discussion / Originality / Re: Battery Side post or top question on: April 20, 2013, 08:56:09 AM


My 06A RSZ28 has the original side post cables, it was made approx June 20, shipped June 23, ( Canadian Documentation). All June cars are 06A BTW. The original battery was a Y77 with different size terminal threads. My car had the original battery when I bought it, it has a Delco Replacement and I had to change 1 attachment bolt. I have a NOS Y77 battery for future use.

Those are the "correct missing choke parts"
Accelerator Pump housing looks like it has clutch screws, and the baseplate is the original unreinforced line installed. The choke pull off has been changed at 1 time as it appears to be a straight nipple. Original 4053 has a small bend in the nipple where the vacumn line pushed on. No Big Deal.

If I was to look for those parts would they be hard to find? I have 5 sheets a friend gave me in 1975 from a HOLLEY CARBURETION VARIABLE SPECIFICATIONS AND PARTS counter book , page 81 and 82 showing the 4053 carb numbers, page 240 that has the exploded view of the 4150 TYPICAL VIEW ILLUSTRATION NO 34-1, page 241, 243 with part names and index numbers.

Fast idle cam is (136)41R-539 and the fast idle lever is (6)4R-852. The missing screw is not found. Just wondering if if I should waste my time on this or let it go.

Al at Chicago Corvette will have those parts, but they are probably expensive. I was reading the sellers reply, he doesnt have a clue what he is talking about, they dont use a screw for the fast idle, the missing lever has a tang that is bent/adjusted to set the fast idle on the Fast Idle cam steps. They are not $10. You should insist he post a picture of the drivers side of the carb, as well as a under neath shot, its no trouble to add pictures, if he doesnt want to comply dont bid. I have seen many DZ carbs with the later issue reinforced baseplate, (originals were prone to breaking on the LR corner) plus the wrong accelerator pump housing and lever, originals use clutch screws., plus ask him the secondary metering block number, it should be 4519

Once again engines were furnished to the assembly plants without carb. The inventory of carbs was there, not at Flint so the carb date is unrelated to when the engine was built.

There are 30-40 known build dates for 4053 carbs covering the 1969 model year. That means they were batch-built 400-500 units at a time. As a Tier 1 supplier there is no way carbs were 'made to order'; they were shipped from finished goods inventory. They sat in stock at Holley; they sat in stock at the plant. There was no first-in first-out requirement. If it was the correct part it was used regardless of date. My data shows 943 carbs as late as August '69.

  

Thanks. Good point.  That may be the case but I posted my carb date/engine build date as a reference so comparisons could be made. I understand that carbs were probably not rotated like groceries with pull dates, and a wider date range is known to exist. The Ebay 4053 Mar 2 week carb in question could probably work for Gary, but seeing as the posted 05E Z28 1,000 serial numbers less has a April 3 week carb, do you think that would be considered normal?

Thanks fellas. I am thinking of putting in a bid for this carb. What do you think? I'm really looking for a 943 but haven't found a core yet in 14 years of looking. Everyone wants to sell me a restored one and I don't want a restored one. I want the patina to match what I have.

http://www.ebay.com/itm/200915392744?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_306wt_1043

IMO it is TOO EARLY, (Read my post above, my carb is 9-5-2 and my DZ engine stamp is before yours), I honestly don't see how a March carb can find its way onto a June car, 2 weeks to 4 weeks is the norm, with 4 even being a stretch.

Seller says - " very nice and the factory choke set up work perfect too",    I don't see how that is possible, it is missing the fast idle Lever and Plastic Fast Idle Cam. You should ask him for a picture of the LH rear drivers corner to see if it has the original non reinforced base plate.

V0604DZ cast date on block is E 28 9 heads are E 28 9 and F 1 9

What is your engine assembly date?

My 06A Z28 ( owned since 73) has the original carb 100% for sure, my engine is VO527DZ and my carb is 9-5-2 ( May 2 week)
71  Camaro Research Group Discussion / Decoding/Numbers / Re: 1969 Z/28 YH Wheels on: April 10, 2013, 03:09:30 PM
Slots on the AD wheels are the same big slots and irregular corners same as original YH wheels.
72  Camaro Research Group Discussion / Decoding/Numbers / Re: 1969 Z/28 YH Wheels on: April 10, 2013, 11:40:44 AM
Great pic's. Is there anyway you could take a tape measure and see what the difference is in the slots? (across and Up/Down) Also how much of a difference is there between slots?   

Original YH slots with the irregular corners are 1&1/8" Height Wise, the FW and Later YH wheels from 9/69 on measure 1". The difference is in the corners as I stated, FW and later issue YH wheels the corners are round. Some original YH wheels the corners are EVEN more pronounced like the 1 below. After you look at them it is actually quite easy to see the difference, take a quarter and hold it in the corners and it shows immediately!
73  Camaro Research Group Discussion / Originality / Re: 1969 Control Arm Alignment Shims on: April 07, 2013, 11:07:12 AM
pictured are the shims I removed from my upper control arm attachments.   The ones on the left are thin (1/16") and the others on the right and stacked up are 1/8" as I recall).    Are the ones without the top tab original? or were they added by alignment shops in subsequent years?

Gary, Pretty Sure they have been added, my Z28 has both thick and thin shims and they are no hole tab type. If you look at the ones in your picture they appear to have a bigger 1/2" hole where they fit over the upper control arm bolt. Camaro upper control arm bolts are 7/16"  FWIW, the Ebay ad shows the shims fitting Big Cars like Impalas , 57 Chev etc, pretty sure those cars use 1/2" upper bolts also.

Here is an ebay link to a pair of supposed 'YH' rims, which to me appear to be very late (after 1969 wheels - one appears to have a '4' yr code).  Notice that the year portion of the codes do not show well in the photos, nor does the ad point that out the full code, even in response to a specific question, they only provide 'month' and 'day' code, and ignore the YR code.   Regular ebay sellers seem to know all the tricks (to fool people)....?

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=230955645839&ssPageName=ADME:B:WNA:US:1123


Notice the dates on these 2 Ebay wheels are read from the inside looking to the outer edge of the wheel? Then Notice that the other YH wheels are read from the outside looking in? Also notice that these 2 wheels have smaller width ( not length) cooling slots with round ends on the slots?  I would be carefull ! Just Sayin. 
 The pictures I am posting are of a KNOWN ORIGINAL YH Wheel, notice the irregular corners at the ends of the slots? not round? and also the date is stamped and read from the outside of the wheel looking in? All Original YH wheels I have personally seen have the bigger width slots and irregular ends up till approx. 9/69., and I have lots of original cars and wheels. After 9/69 the slots got smaller, I think YH wheels were the same for Z28 and Monte Carlo after this date! Actually it is quite noticeable in person, I am going to the shop today and will take some more pictures of Original wheels and re post.

Smaller FW slot or later issue 9/69 on YH slot
