A/C System mock-up - DONE!

I finally finished the mock-up of the A/C hoses and tubing. I had to mount the A/C compressor on the driver's side because the water pump, and consequently the alternator, were on the passenger side. On Detroit Diesels, the water pump is on the side and driven off of the camshaft or balance shaft by a couple of v-belts. The alternator is used to adjust the tension of the v-belts.

Mounting the compressor on the driver's side created a problem - how to route the hoses. I considered going over the top of the valve cover; but, didn't like that option. I decided to go around the front.

Here's a photo of the driver's side showing the compressor and hoses:

Here's a couple of photos on the passenger side showing the evaporator and the hoses:

I still need to take the hoses to town to have the ends crimped on. Once I get that done, I'll be able to pull the system down and see if there are any leaks.
