Can someone tell me what thread the cooler holes of the trans case (not the inverted flare for the steel lines) are? I believe they are 1/4" NPT but I'm not sure and I don't have my car with me to check. I am switching over to braided cooler hoses and want to get the stuff that I need ordered. 6AN? Thanks
