Crank and Water pump pulleys

I have some pulleys that are left over from a project. Some of them are single and double groove crank pulleys that were used with the short water pump. Were these years of trucks using a short or long water pump? I need to sell some of this stuff but I need to target who needs these parts also.

For the Chevy/GMC truck models (both SB & BBC), 1972 and prior models were short water pump setups and for the Chevy car line, 1968 and prior were short water pump (LH/drivers side mounted alternator). So, change over model year to V-8 long style water pump bracket/pulley setups (RH/pass. side mounted alternator) would be 1973 on the GM trucks and 1969 on the Chevy cars (excluding corvette). Mel
