+1 for stock routing pics
I too am with Franken on the need for some pics of the stock A/C hose routing system layout:
Someone here mentioned that the compressed side runs from the engine bay down along the tunnel (where the speedo cable is?) then up to the condensor. I think then from the condensor it runs thru the frunk (right side) to the dryer - the entire works covered in a plastic cover - then back under the battery (LH drive cars) thru the top of the rack/pinnion unit and into the passenger foot area. Turns towards the heater box, where it hits the expansion valve attached near the inlet to the evaporator. Return from evaporator goes on the outside of the tunnel (passenger side) back in the spare tire area. I can see there are metal loops unused on my originally non-AC '76. Somewhere between the evaporator and the AC compressor is the frost prevent valve, but I've no idea where.
My donor AC car had half of the components I need removed - only have the AC heater box left. Since I'm doing a K20 conversion, I'm definitely using Larry's information and parts list to make this work, along with a stock K20 compressor.
It would be very useful to see the plumbing routing if anyone out there has it. I've seen that requested in various threads lots of times.

Franken said:Larry can you tell me a little about the standard pipework routing? As we never got A/C cars here I don't have any reference point - apart from some fuzzy pictures in the factory manual!
I regularly refer to your system drawing but I'm not 100% clear on some of the hoses run - eg the one from the evap to the frost prevent valve - does that run in the cabin? Down the tunnel? through the sill? And the one from the dryer to the TX valve - does that run over the steering rack? Or under the floor? If you have any photos they would be invaluable also.
Sorry - I know these are probably obvious questions but I'm flying a little blind here!
