If there are adapters on the dryer, and the high side line it would be 134, otherwise there is not a good way to tell.  I had issues with my fittings so I charged with the factory fittings with a 134 can.

If in doubt, have the system converted by a VERY reputable shop, and make SURE they changed the accumulator and orifice tube. R134 does well with a variable orifice, but I've had problems with them not sliding in the evaporator tube all the way and then breaking off when you try to remove it.
