Thanks for the tip. I dont have the part number as the pump is still on the block and functioning (but the bearing is getting looser and worse in the housing each day). It seems every online site requires the make model and year of the car in order to get the part. I ran the casting numbers off the block and figured out it was a 292 made available from 73 - 84. I dont know what truck model the 292 came in between those years so that part is missing and i cant pull the part number i need for the pump.
