This!

The refrigerant you plan on using dictates which condenser you need to use. I buy all my under hood stuff from NostalgicAC in Florida, and all my in cabin stuff from Vintage Air.

NostalgicAC has a much wider selection of condenser sizes and designs, and they are very helpful and knowledgeable in helping design a effective system.. I use condensors that are much larger than what available from Vintage Air to better fill my radiator opening.
