Custom Framerail Installation - Rightous Rear Framerails

The old framerails don't look any better cut off than they did on the frame.

Preparing the new 'rails for their new home, KA Custom tack welded a temporary reinforcement and jackstand platform on the bottom of the step's front section.

In the world of vintage truck customizing, the tape measure is an invaluable tool. Kevin positioned the new 'rails where they need to be and measured to make sure they were mocked up at the correct height from the floor. Using the floor jack, he easily raised the rear subframe the appropriate level. Jackstands and the jack made for a solid welding platform.

In preparation for welding up the new rear subframe...

...KA Custom smoothed the plasma-cut frame end's surfaces with the electric and air grinders.

After positioning the custom rear 'rails...

...measurements confirmed the new subframe was the same dimension as the removed component.

To form a solid, flat and square base for welding, Kevin tack welded legs onto the new subframe.

Notice the plumb bobs point to the reference marks from the measurements taken with the old subframe.

According to the level, the to-be-welded subframe had horizontal lines and was ready to be joined with the existing frame ends.

Satisfied the subframe was in position for welding, Kevin ground off the temporary brace.

After tack welding the old 'rails to the new, KA Custom made a cardboard template for the splints that will help join the two metal surfaces.

Kevin cut out the two metal splints with the plasma cutter.

Smoothing out the splints' edges ensued.

As you can see from the three holes in the existing frame, KA Custom planned to Rosetta weld the splint plates in place before laying down the tack and bead welds. Kevin clamped the plates in preparation for firing up the welder.
