Again, sorry for any confusion I may have caused when I made reference to "phosphate black wiper linkage", and any reference to Z28 stripe color overspray onto the wiper linkage. Thanks for keeping me straight! I should have done my homework and re-read the CRG research report (RR) on the 1st Gen Camaro Assy. Process. I forgot that the "Z28" stripes were painted by Fisher Body on the cowl vent panel, trunk lid, and spoiler (ref, Color System, in the Fisher Body - Paint Shop Operations). I had assumed that they were painted in the Chevy Plant toward the end of the assembly line process as outlined in the Chevrolet Assembly Instruction Manual (AIM), pp. 474 - 475. However, please note in the second paragraph, it states....."Z-28, Z-10, or Z11 stripes or black rear end panel or rockers, were masked and sprayed in .....including the cowl vent panel; the spoilers were painted and striped separate from the body and were installed before the body went back downstairs to the Trim Shop".
The RR goes on to state in the first paragraph, in the section, Chevrolet Assembly - Trim Line Operations Details, when the body subassembly left the Fisher Plant and entered the Chevrolet Assy. Plant, "The cowl vent panel was removed and placed in the back seat". One of the first steps the Chevy Assy. Plant did was to glue the end seal on the underside of the vent panel, install the front rubber seal, then attach it to the body after the wiper linkage and motor was installed.
Given this “recommended” assembly sequence outlined in the RR, we can assume that the actual assembly process followed is based on what see on survivor, or unrestored “documented” cars. Assembly sequences often changed during a production run if it saved time, cost, or improved quality and thru-put. This is what makes our hobby fun, yet challenging. It’s like trying to find the Holly Grail - it’s elusive.
The pictures we post of unrestored cars are a great way for us to see what actually happened. I recommend that we try to also state the VIN number and/or build date to “date stamp” our pictures.
The pics I posted are from a true survivor, 69 Pace Car. This Camaro’s build date is “03D”, VIN #NOR283787. Note there is no paint on the back body shims. Next time I see this car, I’ll look with an inspection mirror at the end seal for evidence of overspray paint, indicating a repaint: however, the owner told me that his car is a survivor.
Here are some interesting questions: Were the string of 69 Pace Cars treated differently when the stripes were painted? I must assume that the run of 3675 replicas, (we know not all were assembled sequentially or at one time) put a strain on the In-Line repair booth to paint the Z28 stripes. Painters could not take much time because they also had other Z28’s and SS’s to process in the daily mix. Did Fisher Body decide to start “fixturing” the cowl vent on the body cowl, quickly mask it off, and then paint stripes? Did they begin following this modified sequence sometime during the Pace Car builds on other Camaros?
I have been told by some very knowledgeable Camaro restorers in our hobby that Norwood painted some Z28 stripes with the cowl vent panel installed on the body, and the stripe color did overspray onto the body color in the vent well area. I was told that painters were supposed to use foam to block unsightly overspray from coming out from the front edge of the cowl vent. Obviously, they did not. Quality was not a big deal then as it is today. Some painters skipped the foam to get their tasks done faster which gave them more sit time.
There is evidence (thanks to pictures) that some cowl vent wells were blacked out. See RamAirDave pics. There is also evidence that Z28’s built in Van Nuys did a neater job painting stripes and the cowl vent area. Refer to page 474 in the AIM for the UPC Z28 option, where it states, “Cowl vent grille area will be painted stripe color by Fisher Body”. I was told that Van Nuys removed the cowl vent and painted the cowl vent well and the top side of the cowl panel, out to the edge that interfaces with the firewall. This is similar to what is shown in the pics RamAirDave posted. I have 35MM film pictures of a Van Nuys built, survivor 69 Z28 with the stripe paint work out to the firewall.
RamAirDave, which plant built your Camaro? What is the build date VIN number?
This is all great discussion and informative. I would love to see more pics of survivor cars if anyone out there has any!
