I recently got a pair of stainless steel crossover lines for my HS 33's. Problem is the stainless crossover line takes the one large hole in the slave cylinder. This means I have to press a barb fitting into the line that runs to my lever. WIth several unsuccessful attemps at attempting this does anyone offer a better way. I tried the vice/hammer way (as per instructions) but the barb either cam out of the side of the tubing or split it. Thanks if you can help.
