Review on 🔥 Heater Core for Ready-Aire / Vista-Pro 0399210 by Justin Reese

According to the product description it would fit my 1977 cj5. However, this did not happen. The overall size was about an inch too small. The hoses were also in a different position than the original. Initially the hoses were in an inverted triangle position where the heater core passed through the heater box and firewall. Two heating hoses are next to each other, the drain opening of the box is at the bottom. I used a new heater core but had to change the entry point to the three boxes and fire wall, cut the original top right hose hole to a drain hole, and cut out the drain completely. Flexible hose wrapped around the new hole to prevent sharp edges from damaging the new device. After all of this was completed and I reassembled the system, the heater core worked as expected. Just doesn't fit as described.
