...in my previous ramble, it should say I have trouble because it's "Japanese OR bubble flare or something". Japanese is usually a sneaky metric thread with an inverted flare that can look suspiciously like an American inverted flare. Euro cars like the bubble flare lines. Which are actually easier to make, if you have the right tool (only one step instead of two like an inverted flare...or you can buy a nice hydraulic forming tool and make what you want in one step...but now I'm really rambling).
