Datsun/Mazda/Toyota OEM starters/Alternators

I have 2 OEM Nippon Denso Starters and 1 hitachi starter. The two Densos have part numbers but the Hitachi has no numbers. I also have 3 alternators 1 hitachi with a part number and 2 that are of unknown maker. My dad used to import cars back in the 80s from Japan and replacement parts were hard to come by, hence why I have 3 oem starters and 3 oem alternators. I do know for a fact he imported 2 datsun s30's a RX-7, and a celica all 1970s era cars. I found some cross reference part numbers for the starters but am totally in the dark about the alternators. If anyone would like to buy them or know someone who needs these parts for an original rebuild that would be great. These parts are 100% from japan. They've been sitting in our garage wrapped in plastic for 40 years. I have tested the starters and they do operate correctly. Let me know if you are interested and we can work out a fair price.
