My brother owns a super nice 66 F-100. He is replacing the 3-speed stick
with a floor mounted automatic. He's looking for a steering column.
Does anyone have a spare?

 

You don't need another steering column, you can use what you have.

Take the column apart and remove the two manual control levers at the bottom of the column, remove the shift tube, remove the shift collar...and replace it with this:

C3DZ-3790-A .. Steering Column Extension-takes the place of the shift collar / Obsolete ~ none available NOS

This extension was used on F100/350's thru 1977 w/a 4 speed, 1963/65 Falcon's with 4 speed, 1965/66 Mustangs with A/T & M/T (all 1965/2018 Mustangs have a floor shift).

There were over 600,000 1965/66 Mustangs sold, so the extension is somewhat EZ to find.

 

Yes I do, if your interested

 

I have a column from my 65. Where are you located?

 

Waukesha Wi....a burb west of Milwaukee

 

Ok I can look into shipping costs and let you know. I'm in SE Mich

 

sent you a PM
