Stop in for a cup of coffee

Anyone know if you can get new A/C hoses that screw onto an old ROBINAIR R12 manifold set that will let it work in an R134A syst?
We used my buddys newer set to charge the Duster and it had the adapters to do R12. Even the clamp on thing for cans. I would think you could get an adapter going the other way for the old set...
