I took my dash and A/C ductwork apart about 10 years ago to replace the wiring harness. At the time I thought I would be putting it right back together and had all the fasteners sorted more or less. Life happened and now I'm trying to put all the ducts and dash items back in. I don't remember which screws went where. I can figure out how to fit the various pieces together again but not sure which screws go where. They got mixed up over the years. I can match a few by quantity and associated holes but not all. Is there a list of screw sizes and types and where they go? Fortunately, I finished the wiring before life got in the way. Retired now and not getting any younger like the truck.

If someone has reference photos when they took their dash apart that would be very helpful. I didn't do that. Duh. I assume any square body would be the same as the '81 under the dash, more or less.

I appreciate any help in advance. I know I'm not the first one to face this on a square body. Heck of a truck.
