Charger 68 R/T A/C Question

[Gentleman]

Hi,

I try to restore my 68 Charger R/T with A/C option.

I Need some help on the compressor.
Which Pulley and Hub is the correct one? I need a double Groove one. I found the following:
- Warner Warner
- Pittsburg Type

I found pictures of many Chargers, that have the Warner style. There are two different types.
One has an O.D. with 6 1/4 and one with 7 1/4. Can anyone tell me which one is the correct one?

Thanks a lot

Quick google search seems to point towards the 6 1/4 as being correct.
