Review on Hilitchi 123Pcs Hydraulic Fittings Assortment by Joseph Pudic

Well I got these specifically for 6mm 90 degrees and neither of them fit while the other two versions of the 6mm screw fit well. So you seem to be the wrong thread, or maybe a little wider. Also, the Zerk heads seem to be smaller than the stock heads and I'm having a hard time getting a good connection with a straight 6mm or any other curved 6mm version. For me it was a waste of money and now I have to buy more mirrors elsewhere.
