Hi i'm new to this site i'm restoring a 1971 K5 Blazer mainly for show not go it's mainly all stock it has the CST package factory air and factory 4spd it didn't run when I got it so I built the hell out of the motor just interals it looks stock on the outside. What I am wondering is I know its a rare find but how rare. Thanks for the help guys!

There were approximately 17,220 K5 Blazers produced in 1971. You might want to check out the 69-72 K5/Suburban/Truck section. I've got a 1972 K5 4x4 CST with 3spd automatic. Also factory air.
