Hey it'* JDB, not John D.
I did a complete change, pulling a full vacuum before adding Freeze12. I believe the instructions for Freeze 12 say you must do this. You are right, the Freeze12 fittings do not match R12 fittings because they want to make sure you do a complete evac by making you put expensive Freeze12 brand adapter fittings on your car. I wish i could remember exactly what i did, but this is what i remember:
First, 93 bonnevilles have a funky High Side fitting, and i had to buy an adapter at Carquest to make the high side fitting fit my R12 Guage.
Second, to make the Freeze 12 can fit my R12 can tapper and guage, I welded two nuts together...one nut that fit the Freeze12 can, and one nut that fit the R12 can tapper that connected to the guage. The nuts did not have to be airtight because the rubber Oring on the can tapper does the sealing. The nuts only had to keep the Oring clamped to the can. If your tapper is different than mine, this may not work for you.
