Super 10: A new year and a new project

In this view, some items to define. 

The build up is using a Chevy 12-bolt rear housing. In this photo the housing is not yet cut to final length, that will come later. The factory bearing ends have been cut off to allow the four link brackets to slide in place. The housing is “over length” for now allowing plenty of side-to-side adjustment. 

The pinion will be offset 1” to the right so that means the forward four link cross member center line is 1” to the right. This 1” offset mirrors the engine positioning. 

The four-link hardware is a package from Chassis Engineering that includes detailed drawings giving specific location for all brackets. 

Also notice the temporary cross members and center string. 

You can see the shock/ride height tubes. They are 1” x 1” tubing with bolts holes at 13.750” center to center. 

Notice all of the original frame still in place.

This photo begins detailing the new rear frame section.

There are a number of things to notice in this photo. Just noticeable is the construction table. I built a 2” X 2” steel tubing frame with ¾ plywood top. The table is 24” high. The 24” height worked out as a good compromise. The table becomes the ground line for all suspension measurements. Later, as we move to the front section we will see another 24” height table there. Also notice the new 2” x 2” x 1/8” frame is built inside the original factory frame. Doing so gives a good reference and alignment for building the new frame. Once the new frame is completed the original factory outer rails will be cut away. 

Measure, measure, measure, double check, then measure, measure, measure. You will notice several temporary cross members and a “center string.” 

The frame appearance is usual because of the bed mounts, which stand well above the frame rails. Those mounts will remain and once the new frame is completed the bed will bolt back down on the original mounts.
