Finally bought my dream car. 1972 firebird with Ram Air hood scoops (cosmetic only) but have many questions. Body is solid, paint and chrome are a 10 out of 10. Interior will need some cosmetic work. This car came with a 350 with air conditioning but now has a 400 in it. How hard ($$) would it be to add air conditioning as it once had it (vents and AC switch etc)? Looking forward in starting the journey!
