They fit right on my 79 Impala. The top hose is a different shape than my 79's, but it lines up perfectly with the rad inlet and the thermostat housing. The bottom hose is identical, and even the heater hose fits!
I know a person that has a set of these for their 84 Caprice too.
Here's a few pics:
Because these are so rare I have to get $175 for them. That includes shipping to the conus.
I also have a complete set 0f 9C1 hoses for Bubbles/Impala SS with the LT1's in them. $100 for the set.
