1969 1/2 A12 Alternator pully question

I just sold my A12 4 speed car and the buyer has asked me a question about the alternator pully. He thinks it might be a double pully, but I told him I think it should be a standard single 2 1/2 inch pully. I have searched the parts book and it looks like it is a single pully to me.

Does anyone have a picture or know specificially what is correct?

It wasn't a double pulley .

Single pulley is correct. Hemi's have a double pulley.

Many thanks to all who responded for the information.

Unless it was changed, the correct pulley for that application is 2444478 - 2.5" single groove.
