My friend's dad is doing this for me, but has only recharged other makes. I wanted to see the correct ports for myself because he may not be familiar with where they are and learn something.

Ronman - thanks for the pic. My 67 looks different though. Don't have that fitting in the back.I also don't have the fitting on the larger "muffler" piece that yours does. Does the FSM show good pictures of this? If so, I will go ahead and get one. Thanks, all. I appreciate the replies and help. I just want to see if it works if I can do so safely and before I spend a lot of money on an r-134 retrofit just to find out it still doesn't work. Blair.
