Using 72 A/C hardward on 74 Duster?

[zig]

My 74 Duster came with factory air. I am putting everything back together and would like to upgrade a few things on the way... I found classicautoair.com. Their application is 67-72 Duster. I am wondering if anyone has used earlier Duster parts on a 73+ car? The a/c did not work when I took the car apart. I need new lines, would like a new evap, new/rebuilt compressor and new dryer... Looking at prices on there, they seem reasonable compared to rockauto and such where it will cost near $00 for a rebuilt compressor with clutch...

Any thoughts or other options?

Thanks for the input....

i called them and there product is for non a/c cars only. the firewall is different between a/c and non a/c cars. they say it will not work in a a/c car.
