AC high pressure port

[TheYak]

Hi guys, does anyone know where to find the correct fittings to convert to R134a? Long story short, my car was previously converted but loses its charge every year. I finally had enough and bought my own vacuum pump and gauge kit, going to find the leak and do it myself. However, my high pressure port look like this (see photo) and the amazon R134a conversion fitting does not thread onto it. I'd appreciate any help, it's hot as hell here in Florida. Thanks! - Mike

That is an R134 conversion fitting. Somebody's already been in there and tried to convert it.

I found one, thanks. Autocraft p/n AC995 for anyone who might run across this post later.
