Anyone swap HVAC unit from donor?

I’m sort of thinking along the same lines. The reason I’m interested in using a neon box is because I plan to swap an SRT4 engine into my 67 Valiant, so I may as well use the rest of the A/C system as well.
Even though I am currently installing a vintage air to a stock magnum I sure do believe there is something nice about having the hvac system stock even if you have to hack the box etc. It's proven to work. I'm just not a good fabricator so I wimped out. But I'm also doing a delete dash so the remote solenoid switches from vintage I plan on hiding in an armrest.
