Lot of NOS GM parts 1950-1990's? 10 pieces

Description

Just went into the back of my old swap meet cube van and pulled out a box of NOS GM parts. I have researched and posted all the items that I could identify and these 10 items seen in the photos are parts that I cannot identify what they fit. Some have superceded part numbers and some I cant find any information on. There is a mix of electrical, transmission gears(have some rust on them but should clean up with a brass brush), some Delco electrical and one accessory box(one in last photo). This part which is a wiper washer synchronizer has the end flap gone and may be missing some hardware but has instructions and main parts present. Some of the pieces appear to be from the 50's and some of the newer boxes have part numbers that would indicate they are probably from the 80's or 90's. Any one of these pieces could bring what I am listing this auction for!  WYSIWYG! Thanx
