If you are planning to use the R-4, new barbs will need to be welded onto the compressor manifold, and to the special fitting on the TXV. What I have done in the past, is to weld on a male Oring fitting instead of a barb on whatever factory manifold/fitting that is retained. That way the hose assembly has new Oring fittings on both ends, and can be easily removed/replaced without cutting off any old fittings. Of course I always suggest retrofitting to a Sanden, and replacing all the hoses (except liquid line), and changing out the factory condenser to a Parallel Flow.
