A/C question...

Now I no ya'll gunna say A/C ain't a performance update, but when ya old like me, it iz when ya live down south...

I'm transfer'in tha A/C from a 71 dart, to my 66 dart wagon...I want to paint tha main body so I kan insatll tha engine compartment stuff, and the front end and rearend...It's on tha rotisery now, and it will be easier to paint now...BUT I don't wanna run into any unexpected crap and have to cut my freshly painted fire wall, or dash...REX
