I have a 68 Deville with a 472....I was replacing my compressor recently and when I went to change the AC drier I realize that the drier connection (it connects with tubing) is diferent from the drier connection thats offered for the car (it's a screw connection) Is there anyway around this without changing the hoses out?

I have found that some NAPA stores can fabricate new AC lines to your specs. The pricing is better than those specialty AC shops.
