HOW TO MAKE A DD SHAFT

A DD shaft is a round shaft with ats centered on two sides. If you are using your original
gearbox you will need to modify the shaft in order to install your ididit steering column.
An easy way to do this is to make a paper template. Create your own template by using the
measurements from the diagram below.

1.000”

Note: Diagram not to scale

.395

.945

1.525

2.075

2.356

Starting from an 1/8 from the bottom, wrap the paper template
around the shaft and match the horizontal arrows together.

Mark the shaft at the 8 vertical arrow points and draw a line down
the length of the shaft, connecting the marks. This will create the
shaded “D” sections found on the template.

With a grinder or similar tool, grind at the shaded “D” sections to
match the DD shaft. As you work, use the coupler as a guide and
test t to ensure proper tting.

Another option would be to remove the gearbox and take it to your
local machine shop to be modied.
