Yes, those are the original hub caps that came with the car. In 1977 my Late Uncle put on Appliance mags. They were still on when I started the restoration. Luckily, he put the steel rims (two had snow tires on) and hub caps in the basement for safe keeping. He did the same for all other parts....like the console 8 track, space saver tire, etc.... he installed a Sony console mount cassette player (which was stolen in 1980). From what I understand, this design "deluxe" hubs cap was only on the '68 model year.

Funny story I will share. In 1987, someone try to steal the car out of the garage. Now the car had no battery in it and they could not get it started. They were so dumb, they cut the wire harness up the steering column thinking the ignition was there. So, they tried to push her away....like a theft in slow motion. We found her a block down the alley. I guess they got tired....LOL!!!.
We put a battery in and drove her back home. After that, my Uncle had doors installed on the garage and she sat unseen. If a battery had been in her......she would have been gone for good or smashed.
So during the restoration, I found the cut harness that I had spliced together back then and replaced it with a new one.......memories.

Regarding the engine running "lean"......is this something I can adjust..?. I'm am not a mechanic but, can do basic things. Am I damaging the engine like this..??.

i did not think about replacing the quarter windows as we only found out now that the decals have to be removed. I may do just that. However, everything would need to be opened up again in order to do so.

I mentioned in a previous post that a second build sheet was found. P's seem to have been added to this other sheet.
I am posting them both here for your information.
