Adding factory A/C system to a non/A/C car (66 Barracuda)

[djpearce]

For those of you who either have a factory A/C 66 Barracuda or have already added the factory set-up, does the lower pully (on the crank) need to be changed out as well? I have a few factory systems I've picked up over the years, but I don't recall if in my parts horde I have a different crank shaft pully or if one is needed.

Thanks for you wisdom on the subject

Thank you for the info and picture - looks like I'll be posting in the "part wanted" section to find one!
