Looking for advice on A/C

:thumbsup::thankyou:
Hi all,
Just picked up a 64 valiant system off E-bay haven't got it yet but I need the pulleys and it look like it's was on a latter style 225 and I have probable 63 -64 225 in my 61 lancer do those lower pulley/balancer mount differently. I know that they were dealer install items could the extra pulley just bolt on to the balancer?
Thanks
Larry
