Late model master cylinder fittings?

You can clearly see you have the one on the right. You need the style on the left. Your thread pitch is also wrong . It will fit but loose. Jus buy the master line set for your car from inline tube. Or ebay below

You can see the tapered section in the fitting I have in this picture. I can’t use the line set, the linelock requires a handmade line
