GLPerry my wheel cylinders have a block on the back that the hard line screws into the block is screwed into the wheel cyl with a banjo bolt into the lower/back cyl then out of it through the crossover tube to the front/upper wheel cyl then that one is the one you bleed since it is the highest point for that wheel. and the old and new wheels cyl all have this diffrent thread for the crossover tube to screw into. I thought standard steel line so standard threads.. "NO WAY" and dont try screwing a regular line in them and altering the threads.. (it breaks the wheel cyl housing) so would anyone care to look around at where ever and find some new or a old used line with good nuts in a 7/16x20 threads....PLEASE
