Hey Chengy, I just did a conversion on my AC in my 87 K5 bkazer. I had followed a thread from 2014. Replaced every component except my fan. My AC blows about 56 out of the vents. My low pressure lines, accumulator and evaporator are gettin alot of condensation and them and are getting very cold. Not sure if this is normal. Do you have any words of wisdom on this? I put 50 oz of refrigerant with 7 oz of oil.
