Oh, yea, we had to do that with our car a couple years back. When David gets back (moving wood from the boatyard to our storage garage...) I'll ask him where we got the right stuff--seems like it was someplace online specializing in these things. I'll get back to you later on that....We had the vac pump and gages for use with home systems and automotive systems and I recall there are a few different fittings to choose from. Of course, all that stuff is in storage in Maryland...
Also, you can track down your system's manual Adler Barbour is also WAECO, which was purchased by Dometic... google?
Finally, you really need to be sure that the new refrigerant is sufficient for your older system. R12 is more efficient, so you're system will have to be oversized a bit to work very well with the R134. The only way you'd know this is to get in touch with the company, or if it was standard equipment on your boat, the users group.owner group for your boat may help out there, too.
