Hello all! I'm located in south Florida near 33334 and I'm looking for the Afco Dual fan heat exchanger. If I have to settle for the dual-pass (non-fan model) I will, but would prefer the one with the fans. Also, I have the stock reservoir tank for my coolant and would like to upgrade that. Looking to save some coin, so used is cool with me. Let me know what you have. Thank you!
