      The dual lines were part # 4462745 - no Google hits either.
      The discharge line # 4462149 looks like both hoses together and got an e-bay hit:

      I agree that the old refrigerant hoses may not be very reliable with R-134a and may need to be updated with new hose. If you can save the hose ends, a length of generic R-134a compatible refrigerant hose could be cut and clamped to the ends.
      The Chrysler TSB # 24-01-95A for converting R-12 systems to R-134a (the right way to do it) would be incredibly expensive to do as it asks to replace many major components.
      "Hybrid" refrigerants and oils that claim to be safe with either system may actually damage some components and introduce leaks.

      Thanks for that ebay link. I need to do some more research. It's funny that they list that one as fitting the v6 also. I am now wondering if the v6 listed hoses really would fit the 4cyl afterall. I would never buy that NOS one for r134a, but I am hoping if the aftermarket v6 hose does fit, that they are using the better barrier type hose when they are making them.

      P.S. I just looked up the v6 hose at Autozone, and they do say it is the barrier type for r12 or r134a.
