The upper tag is a verification tag that gets punched by the assembly line worker/inspector just before the Jeep heads to the paint booth. He/she verifies the VIN number and paint code before sending it into the correct booth for spraying paint. It would be a major screw up if the paint applied was a mistake and did not match the paint code on the VIN firewall tag.
The tag is usually affixed to the VIN firewall tag by one of the pop rivets. The line inspector merely lifts the tag and makes a punch mark on one of the letters which I do not know what they mean. Perhaps time of day or work shift letter code. But each inspector has his/her unique punch that verifies who did the inspection. I don't know why your tag has so many punch marks but, perhaps the inspector was having a happy thought at the moment and just went crazy with the punch.
I saw this take place in 1982, when I took a private tour of the Jeep Toledo Ohio assembly plant with my uncle and remembered it. There was a huge paint booth at the plant and I watched the inspector reach into the engine compartment with his punch and then direct the Jeep into the booth. Before going into the paint booth, the Jeeps line workers applied body seam sealer to most of the seams on the Jeep body where two pieces of metal came together. But not all of them.... rust.
When you did the Toledo plant tour, did you happen to ask anyone why they chose to install things like the roll bar, mirrors, and hinges before painting, so that those areas would rust faster than other parts of the CJ? I've never understood that.
You're looking at this all wrong. What this actually was, was an effort by AMC to stimulate the economy; and this effort has been successful beyond even their imagination! Look at their cost savings at the plant PLUS all the job opportunities in the automotive industry from parts manufacturing to warehousing to sales to repairs and painting! AMC saved us!
It was a stroke of genius!
You have to change your perspective, my friend, (Glenmorangie and a cigar help. a LOT! )
I'd rather be lost on the trails than found at home!
HaHa. Yeah, I guess if every car lasted 30 years without turning into a rusted pile of *****, our economy would tank.
So, who out there is familiar with the molding/manufacturing process to make a decent set of rubber parts? I've seen how certain injection molded plastic parts are made, but not rubber. How expensive would the tooling and startup be?
Moulded rubber is quite easy, you can do it by injection moulding. Latex or the synthetic equivalents is injected and cured by heat and also under pressure to drive out air. Start up costs are probably similair to plastic moulding.
There are other ways of doing it including laying latex on to a form, adding layers of reinforcement, more latex etc and then curing in the oven. This is good for moulded parts such as gearshift gaiters and flexible couplings. You can also create moulds of parts and then fill them with latex etc.
The problem is that whilst you can with some work produce nicely moulded copies of hard to find rubber bits, it i s not so easy to get the correct hardness for suspension bushes etc. It takes some knowledge of the chemistry and processes.
