I like to know if you can get the rest of or make a complete unit out of what I just purchased on ebay. It\'s the old Mark IV unit that came out of a 1976 Chevy Vega. I would very much like to have it retrofited with the new refrigereant. What I have is the control unit with the vents with out hoses or receiver/drier, pully for a 140 cubic inch Chevy Vega motor. I heard these are what lot\'s of people were putting on thir Cosworth Vega for nice air. Can you help?

bought this antique camper, in it was this above unit....the evaporator housing and duct work is fine, but there is a missing part on the evaporator, it seems to be a piece, I think the expansion valve, as the pressure line was hanging loose, and both ends, on the coil and on the hose seem identical flare fittings....so I don\'t see any expansion valve, but I do see a control like for temp, at any rate I need whatever is used to connect those two fittings together....also that old York/Techumsa compressor is locked up, so need a newer style comp that I can mount in that essential location, can you recommend something from another common car??

I have a 1987 Holiday Rambler Aluma-lite motorhome. The heater core is leaking and I need a new one. I found some literature in the manual that came with the motorhome. It has a diagram and a parts list for a 07-100 heat/cool unit with the name John E Mitchell Co. on it. It is 15 and 1/2 inch X 6 and 1/4 inch X 2 inches nominally. Any help would be appreciated.Larry
