I have a Cutlass with air conditioning which uses a cross-flow style radiator like the Jetfire. I have been able to find the lower hose in a molded style on EBAY. I have been trying to find a molded style upper hose for several years now. I took my old molded upper hose to a couple of auto parts stores, who will take the time to try and find a hose for another application that might be close, and had no luck. I decided to keep the old hose because it looks correct. I kept a universal type flex hose in the trunk in case of emergency. Well, it finally blew out a couple of weeks ago and I’m now stuck with using the flex type hose.
If you find a substitute that looks like a correct original please let everyone know. I’m sure there are other owners who want to keep their cars correct in appearance.
