GM part number for door latches

[Silver Square]

Looking to buy some NOS door latches for both doors on my '77 K15, but I'd like to search for them by the correct GM part number so I know I'm getting the correct ones. I've seen them listed by several different part #s on eBay, so it's kinda confusing. Does anyone know what they are for each side? Also, I have heard that the exterior door handles on the very early trucks, '73-75, I believe, used a better quality all metal exterior door handle. Does anyone happen to know the GM part numbers for those? Thanks.

I'm assuming that the part numbers were superceded a time or two, so looking for NOS latches is probably going to turn up a different number, depending on how old they are.

I also would not be surprised if the earlier style handles were never sold over the counter, once the design was changed in '75 or whenever. Most likely, the newer style handle (hollow backside) would have been sold as the direct replacement part for the earlier trucks too.
