I'm trying to put all the a/c stuff back on my 70 Challenger convertible. does anyone know if all of the parts are the same from 70 to 74. Like compressor, condenser and lines thanks

Some part numbers may be the same, but on a small block car the suction line (compressor to firewall), and the line from the drier to the condenser and the condenser itself changed at some point - not sure exactly when it changed, but here is a picture of a 70 and 72 small block with ac. It always amazes me on these cars how much stuff is 70-only. Seems like almost everything is different between 70 and 71-74 when it comes down to the fine details.

I have an extra small block '70 compressor, suction line, and condenser. Possibly some of the other pieces too if I dig through my stuff a little bit. PM me if interested.

Small block or big block?

I pretty sure a small blk. compressor is different than big blk. doesn't have as deep a sump on the bottom.

Yes the compressor is different. I'm really hoping to find someone getting rid of there whole under the hood a/c components from a 70 small block challenger, as the condenser and lines are specific to 70. And I will need the brackets and wires. I have the heater box and dash as the car originally came with air.

I took the lines of my '70/318 Challenger when I switched to BB+Sanden... I'll look around and see what I still have.
