Hurst 5671510 Brake Hydraulic Line Lock Kit

Being universal, not GM specific in my case, your going to have a bunch of useless adapters. I wanted to install my roll control in between my master cylinder & proportioning block (70's GM pb car). If you're going to do this you'll need one more 3/16" x 5/16" male inverted connector. They are pia to find too. Make sure male end is same length as one in kit or it will not seal! Technically you're supposed to install after proportioning block but to do this you'll have to block one front brake line, run a tee off other front brake line, and connect both front brake lines to the tee. To me this is just more plumbing, more places for leaks and I prefer having both lines getting pressure rather than one line into two. The Hurst roll control has four ports and comes with just one plug. Probably need at least one more 3/16" flat plug depending on your app. It would've been nice to have car brand specific kit with two brake lines with a 3/16" fitting on one end and a 5/16" on the other end. Also, steel fittings, rather than brass, for brake lines is better.
