Re: 1968 GMC - Ol' Blue

I've been messing with power steering/hydroboost lines for the past couple weeks and waiting for parts - more on the hydro lines soon.

I only had a few hours this weekend to work on it but that was enough to get the instrument cluster assembled and wired up. It was a pleasant surprise when the gauges showed up just in time for the weekend and that the minor gauges (temp, oil, volts, fuel) just plugged into the major gauges (speed & tach). I should have taken a picture of the back of the cluster, but it was pretty easy. What I like about New Vintage is that you don't have another box to connect everything to, it all goes to (2) pigtails which plug into the back of the gauges. I mated those wires up with the (2) gauge cluster disconnects on the American Autowire harness so it's pretty clean.

Also got the brake lines finished. From looking at the donor vehicle and my research, the front port goes to the rear brakes and the rear port goes to the front brakes. This is the Astro hydroboost/master cylinder/prop valve. The donor vehicle was disc/drum so I'm hoping it works. The brake line that goes to the rear brakes threaded right in, but I had to get a reducer bushing for the front brake lines. I didn't cut or reflare anything on these lines, just made minor bends to clear everything and line up with the prop valve.

I should get my replacement carpet tomorrow so I can put that in.
