Just purchased this, so I haven't got it yet, but I've found a UNICORN! It's a 1981 Cutlass A-body Product Description Manual, aka PDM, aka Product Information Manual (PIM). These are commonly referred to as Assembly Manuals. They basically show you HOW the car was supposed to be assembled by Oldsmobile, with engineering part numbers (not always the catalog part number), installation tips, etc. Many of the diagrams are watered down and used in the CSMs, but they don't always have the same detailed information as the PDM has. There are details used in the PDM you can't find elsewhere. This is an excellent resource to help reassemble your ride once you take it apart and then can't remember what goes where and how. It's only applicable to the 81 model year, but since 81-88 Cutlass is pretty consistent in the builds, I'd say it's pretty valuable go-to to help with other years, or get it close. Not all will be the same, but generally, I couldn't be happier. A 1984 or 85 would be better, but I don't even know if they had those. This is the first one I've ever seen for the "newer" G-body body style Olds. I did see a 79 one once.
