Race Steering Column To Aid in Header Clearance

This is more of an FYI to help anyone that is building a race setup or not

interested in using a stock steering column. I just bought a dragstrip only74

Duster a few months ago that needs some upgrades and improvements. Along

with the many upgrades I am making is totally removing the OEM steering

column and going with a 3/4" DOM steering shaft and a u-joint on the steering

box input spline. This will allow for more header clearance and make it easier to

remove later when I need to service various items. The main reason I wanted to

share all of this with you is to enlighten FABO members to the spline diameter and

tooth count, so this information will make it easy on the next guy. The manual

uses a 3/4"-36 but it measures .730" on the O.D. and it is not of the same

pressure angle as most 3/4"-36 joints, so you have to be careful when buying it

to make sure it's for a Mopar spline and the power steering box uses a 5/8"-36

spline u-joint. However there are within the industry there are 3 different size

5/8"-36 spline u-joints so this is where I will help you avoid getting the wrong

parts.

They come in 5/8"-36 .600" major o.d., .605" major o.d., and .620" o.d.

The Mopar uses the 5/8"-36 .620" major o.d. spline. Stiletto Rack also is the

same one.

Personally I like using American made Sweet U-joints rather than cheap Chinese

made u-joints when my life and that of others is in question.

Here is the part numbers you need:

Sweet Mfg 401-50607 Steering U-Joint 5/8"- 36 Spline x 3/4" Smooth

The cheapest place to buy it is on eBay from a speed shop in Terre Haute,

Indiana of which I have purchased several Sweet u-joints from

for various projects in the past.

Hope this information might help others along the way.
