Don't know about retrofit but, an original r12 system in good working order should be plenty cool in a regular cab truck. Our C30 shop truck will just about grow icicles if you let it run long enough.
We replaced the o-rings and soft lines with repops from lmc, poured some oil in it, e-vacc-ed the system down to 300 microns and put the recommended charge ( 2.75 lbs I think) back into the system. It blows COLD.

It is crucial that you pull vacuum on the system before you charge it.
You might reach out to your local hvac guy and see if you can get him to top you off with "Hot-shot" , that stuff works great in R12 systems.
