Heater hose assembly

I cannot remove the T-40 bolt that holds the heater hose assembly to the frame of the car. I watched your video, but it only recommends removing this bolt but does not show how to get to it. I have tried several tools. The 3/8 drive ratchet with T-40 bit is too big. I have tried using a bit ratchet, but they are too short and not heavy duty enough. I broke one already. I tried loosening up the AC compressor, but couldn't get it to move out of the way in order to get to the bolt. Is there a method or special tool?

Also, in the video, you replaced the entire assembly. My local auto parts store only carries one of the hoses. Rock Auto carries three out of the four. I cannot find the entire assembly. Where did you purchase the entire assembly?

The heater hose assembly has two metal pipes with rubber hoses on each end. Pipe 1 to heater core, pipe 2 to heater core, pipe 1 to engine, etc. The hoses appear to be crimped on these pipes. Hopefully I can remove the old hoses and reuse the pipes with the new hoses. The other issue I see is that the hoses attach to the engine using a plastic clip and connector. The video indicates to twist and remove the hose from the engine. That is the easy part. The video shows heater hose inserts attached to the engine. The hoses I received from Rock Auto do not have these inserts and I cannot find them anywhere. Did these inserts come with the assembly you purchased?

Thanks
