I checked out the valve cover more exactly today. There is a manufacturer's number inside. I do not know what it stands for.
After searching the bolt that holds the clips on the rear leaf springs with 30+ mopar parts vendors I did my own bolts. They turned out ok. I need to get help from a friend of mine to get the threads.
The driver seat tracks starts to get finished. But I do need the inside bottom bracket. It is so bad and pitted.
