My ac is not blowing cold and I cannot get R14 anymore. So, I will have to bite the bullet and do the R134a conversion. What is an updated drier-receiver part number and where to get it? Either online or at a brick and mortar store. Mine says Parker 16599 3 on one label And 4121 on the other side. These are close in size to a VW Vanagon 1984, but the fittings do not match. The newest part number I could find on the fchat forum was 1) Receiver/dryer Car Quest #208625 Shows as not available any more in Car Quest. Thanks in advance 1984 Mondial Cab US model.
