My 84 truck has a sticker on it says converted to freeze 12. I was able to get a couple of cans of the "freon" but am having trouble finding the proper fill hose. The low side fitting is a standard righthand thread aprox 1/4" flare and the high side is a lefthand tread of simular size. The can has a small 1/8 pipe aprox type tread. anyone shead any light on where to find the correct adaptor so I can get some freon in this thing to see if it will cool? Getting warmer by the day 85* today.
