No 53-55 Chevrolet light truck came from the factory with a brake booster as standard equipment or as an option/accessory.
Larger trucks (4100 series and above, 1.5 and 2 ton) had a hydro-vac "booster".
What size of truck are you interested in?
What series of truck do you like (based on style/appearance).
Do you want a mostly standard equipment truck, or do you plan to modify it (or plan to buy one that is already modified)?
Or, what features in a truck do you want (engine, drive-train, . . . , whatever).
