Tuff Wheel installation

[headejm]

My car is 1970 Challenger with the standard steering column and steering wheel. I'd like to ad a Tuff Wheel just for comfort and to aid in steering.

What do I need (besides the Tuff Wheel) in order to install the new wheel? I don't believe it bolts directly to the column without some extra parts. Thanks!

I believe  they are a bolt on.

My 70 Cuda was bolt on, the horn button different.   Since there is a gap you need to go to Nupar for the right one

Do I need this installation kit?

  Does your current wheel have this horn switch?  It appears to be standard for most mopars of the era.
  If so I believe all you need is an appropriate button.

Nope.

Grant 1004 leather wrapped steering wheel. Yes, direct bolt-on for factory 3-spoke 1970 wheel. Had to enlarge the hole in the horn switch to accept the new horn button. Other than that, no problems. Can't wait to drive it.

I ran a factory Tuff wheel that I hand-wrapped with a leather cover kit. Looked great for over 20 years but the problem with a Tuff wheel in an E-Body is the Rallye instrument cluster's turn-signal indicators are blocked by the Tuff wheel. The smaller diameter is the issue.

I just installed a repro Rimblow and I can actually see the turn signals!

Curious what you had to mod to mount the horn button?
Thought the Grant button is same size as the factory parts?

[headejm]

The "spring fingers" on the new Grant horn button are a larger diameter than the "spring fingers" on the factory 1970 horn button. I had to enlarge the inside diameter of the factory horn switch. Used a Dremel with a grinding wheel and sandpaper to smooth it out.

Interesting, Thx for the info.
How much are we talking, 1/8" off all the way around?

[Brads70]

It's been awhile but I seem to remember .030" or so....

[headejm]

I'd say pretty close to .030". Trial and error until correct size achieved. Wanted to make sure I didn't go too large because then the factory horn switch would be ruined. I guess I'll keep the Tuff Wheel on for awhile now since the original horn button no longer fits the horn switch.
