We like to get as much detail as we can and so we came up with a mid 70s Air Conditioning Unit that connects directly to our Detailed Motor Insert and Heater Blower Box (found in the "upgrades" listing).
 
This comes with a 3D printed belt/pully that glues to the Detailed Motor Insert. It also has a 3D printed pump that glues to the pully and intale manifold of the Detailed Motor Insert. The third 3D printed part connects to the Heater Blower Box with the included wire.
 
We include a soft steel wire that can be cut and bend per our picture examples or you can search examples on Google. This wire has a rust resistant coating that should be scotch brited to remove the oily coating before glue/paint.
 
Included in the kit are 3 black 3D printed parts and wire. Parts do not come painted.
