B body vs. A body

[Bigcountry]

Hello experts, does anyone know if a 69 B body ac/heater box will fit in a 74 A body ? Are these units completely different animals? Thanks and take care, B.C..

Totally different. 67-76A should be pretty much the same.

Thank you sir. I have a 69 ac setup listed on local cl and had a guy ask if it would fit his A body. Told him I only know b bodies but would ask around. Again thanks for the info.
