AC specs. and proceedures?

I completed a complete overhaul of my 1994 chevy K1500 ac. New compressor, accum. orfice tube and hose set. Did a complete power flush of the evap, and cond. and inter-connecting line. added 2 oz of pag150 to compressor, but need to know how much total oil system takes and where to add it. How much in new accum. any in the cond. or evap.?
