Replacing The Convertible Top Cylinders, And Repairing Rear Quarter Windows On A 1968 Shelby KR – San Diego, California

     Today, I was surrounded by two beautiful 1968 Shelby KR Convertibles and a 2005 Ford GT. It was Shelby Heaven. I just replaced the convertible top hydraulic cylinders, and repaired the rear quarter windows on a yellow 1968 Shelby KR. Tomorrow, I will be working on some electrical and tilt-a-way column on a green 1968 Shelby KR.

     The yellow Shelby had leaking convertible top cylinders that were making a mess in the back seat area. The originals used plastic bushings for the main pivot, but the new ones are precision machined to eliminate the use of the bushings. They go on snug for a precise fit. The hydraulic hoses have been replaced sometime in the past, and they were still in good shape. You have to check them carefully for cracks. The hoses are under a lot of pressure, and will make a huge mess if they blow. Once everything was tight, I bled the system. Everything worked quietly and smoothly. Next I moved over to the rear quarter windows.

     The driver’s side rear window was ok, but needed some lubrication. The passenger side’s rollers had been broken for some time. Before I replaced them, I had to bend the regulator arm back to proper alignment. The rear quarter window regulators rarely break. I have replaced only two in the 20 years I’ve been doing this. Replacing the window rollers, adjustment and lubrication usually takes care of it. The roller come in blue and orange, but both are the same shape and function. If you want to color coordinate, you have some choices. Before re-installing the rear interior quarter panels, I noticed the passenger side lower frame support separated from the rear jamb. It cause the vertical window track to flex back and forth, so I repaired it with a Loctited bolt. They were tack welded originaly, but it is not seen. The last thing I did was securely fasten the window crank support brackets on both sides. The Shelby convertible interior quarter panels are wider, so they added an extension and support bracket. For some reason the bracket was never drilled for a screw nearest the roll bar. My guess is they couldn’t get a drill in the tight space. I was able to use a self-tapping screw with a long drill bit extension. Now the window cranks are much tighter, and work smoothly.
