Demon "Classic Air" AC Install

Hey 6pk. I'm trying to install A/c in my dart with a /6. It was an a/c car so I just got a sanden 508 compressure and brackets off a 85 truck with a /6. I'm using the factory condenser and evap but need to make new lines. My question is, are you using an expansion valve? If so where is it located in your system? Thanks

BTW, your system looks killer Kool.
