Thanks guys. I'm just looking at options right now and appreciate the info.
I'm turning a former street/strip car (more strip than street) into a daily driver and still collecting parts/information. I live in AZ and where I’m at heat and AC are mandatory.
Thanks to your info it looks like I’ll have three options.
Factory AC/heater if I can find good donor.
An aftermarket heat/AC unit.
Stock Heater and under dash AC (kind of leaning this way if there’s room for the blower motor on the engine side of the firewall)
Again thanks.
