You can take the PN to NAPA then ask what trucks it fits. I forget the years but it is a wide range of years. Then buy the best brand you can find.

 

Dont know the part number but they are GM 1 ton cylinders. Napa has them. They fit but you may have to tweak the end of the lines a bit.

 

NAPA PN is posted above. Once you know truck years any parts computer jockey even those without common sense can look them up.
