R134 Freon Pressure in a 1994 P/u

What is the factory recommended PSI for the high and low pressure lines on a 1994 Toyota P/u a/c system?

Does your '94 not use R12? Was it retrofitted for R134?

There should be a sticker in front of the radiator telling what refrigerant and what pressure.

The sticker says R134A but I don't see a capacity listed. I believe the truck came with R134A from the factory. I've had it since 1995 and don't recall changing it.

I must have one of the last '94 trucks with R12 then. I have specifications for R12, but no info on the R134 systems.

If it helps, the R12 systems shows 26.45oz. +/- 1.76oz.
