Air condition readings

OK, I can't find my A C list book. Does anyone out there know the Normal Pressure reading for the High and Low side on the air conditioning system for the 1994 4.3 blazers? Also need to know what the fill level of Freon is.

28 -32 is good low side pressure.
150- 250 high side is good.

Napa Auto parts web site has the air cond oil and R- 12/134a specs.
