Q & A

What's in the Box

It's pretty silly to use plain old steel double d shaft with those shiny stainless steel u-joints. We offer this polished stainless steel double D shaft in 18", 22" and 36" cut to fit lengths.

Speedway Weld-On Steering Shaft Bracket, 8 Inch
                        

Steering column bracket welds to roll cage. 8" long overall, .100" steel, 3/4" slot.

Ididit 1120160010 Shorty Tilt Steering Column, 16 Inch, Plain
                        When space under the dash or around your feet is at a premium, these columns will save you a bunch of grief! These columns have the same dimensions and features as the other Ididit columns, but are about half the length.  

The unpainted finish allows you to customize them in the color of your choice. The columns have the common 3/4" double "D" shaft and accept the '69-up GM steering wheels, adaptors and wiring harnesses and also use the "Swinger" drops on this website.

Use with the under dash mount listed, or design your own mount. Normal installation is two drops at the dash, attached to an adjustable under dash mount. U-joints, shaft and rod end bearings to be determined by the builder.

Unisteer 8050230 Steering U-Joint, 9/16 Inch-26 Spline to 3/4 Inch DD
                        

These polished stainless steel U-joints look great and use a pinch bolt on each end for easy installation. These universal joints are 3-3/4 inch in length and have a 1.650 inch outside diameter.

  • The OD is 1.650" (41.90mm) 
  • 3-3/4" in total length

This size of spline works with Unisteer's Cross Steer Rack & Pinion, Prostock Rack, and Manual Camaro Rack & Pinion and is also the size of manual Mustang Style Rack & Pinions.

NOTE:  These u-joints contain a safety feature that requires the DD steering shaft to be notched for pinch bolt clearance. Once notched, the pinch bolt MUST be torqued to 45 ft/lbs to ensure a tight fit.
