The chassis……well…. the chassis does not differ in any way from the miserable condition of the previously described body parts. Deep rust scars everywhere. The frame was sandblasted, primed and satin painted.
All bushings in the chassis were worn, as were the brake linkages and joints. After I removed all layers of paint from the brake rods, I could see that they were so badly rusted that in some cases only half of the rod diameter was left. I made all the bushings from gunmetal on my lathe. I cut a thread into the bushings of the leaf springs, welded a matching threaded screw to my impact hammer and knocked out the bushings. I made a suitable tool on my lathe to press in the bushings. I remade all the brake rods from stainless steel, recut the appropriate threads at the ends and reused the well-preserved universal joints (forks?). I re-drilled the holes in all the rocker arms and universal joints to the smallest possible next size. I reworked the integrated bolts of the leaf springs on the lathe and adjusted the bushings accordingly.
I found a good answer to the completely worn out front link lever and front brake cable ball joint. I thought it was hopeless to find a replica of this component anywhere. So a good solution was needed that could be made from existing components. I found a ball joint that fits exactly where the old bracket was attached. I had 2 matching extension rods made from high-quality steel because my lathe no longer works accurately in the hundredth range. I found the ball joint in the parts list of a 1980 Jaguar XJ6 4.2. Since I have some experience with Jaguar parts, I also found a universal joint for the cardan shaft... but more on that later.
