We call them a Happy Handle, but whatever you call a hydraulic hand brake it can be fun as hell in the right car. We figure the Mongrel will be that car. In the latest updates from Project Mongrel, we see the Happy Handle go in, the steering column mounted and installed, the seat placed and mounted, and the belt situation figured out with the roll cage’s harness bar. It is a lot going on, but as usual UrchFab shows how to do a nice and tidy and clean installation that works. There is nothing about this build that is machined billet or ultra custom CAD drawn parts, but there is a bundle of clean and simple fabrication that works and looks cool as hell. The two latest videos are below, so check them out and see where Project Mongrel is right now.
