Have any of you guys did this conversion with a older system? I bought the 92 setup with the O-ring pump but I have the inverted flare steering box of my 78. Do I have to buy the AN adapters and run custom hoses or is there a stock alternative that i can pick up at Napa? I haven't looked into the A/C compressor yet but i read you can use a live set from a 3.8 car, anyone run into any problems hooking up the A/C? Thanks in advance for any info.
