Here you go guys, finally a good option for 67-72 c10 dash defrost vents, these are available either with a black plastic face or a billet aluminum option, these use fasteners instead of brittle plastic clips to secure and have the fasteners designed in a way that they are easy to install but still entirely invisible once installed!
This sale is for both sides, you will receive 2 vents, 2 lock rings, and 2 grills of your choice
