1973 450 slc air conditioning

I replaced the compresser, dryer, and expantion valve. I also converted it to 134a while I had it apart. now the lowest I hcan get the low pressure is about 45 lbs. and the lowest temp out od the vents is 70 degrees. The fan on the condenser also isn't working (I just bought it and it wasn't working before).

Any Ideas?
