Re: r-12 to 134a conversion?
Should be adequete. There was a Ford TSB I found a long time ago that had Part #'s for retrofit kits for practically every pre-1994 Ford car, truck, and even commercial truck applications. It involved installing revised parts, different for every vehicle, and in all applications a pressure switch. Your system should work fine the way it is.
