Technical Question on a cowl steering detail...

I've done multiple searches on the Googles and the HAMB and there's a detail with cowl steering that I seem to be missing.
Using a Model A Sedan as an example:
-If the steering box needs to be mounted to a brace that is welded to the frame, how do you put a body on a frame over the brace if the body has a floor?
-Do you mount the body, fabricate the brace and then make the floor around the brace?
-Or Can you make a stout brace inside the body that mounts with some heavy bolts to heavy brackets on the frame?
That's the part of the puzzle I'm missing. I keep seeing Mopar cowl steering setups but I always seem to miss the photo where they have the car finished with the detail of the floor, brace and frame involved. I know there has to be loads of people here that have done it, that can show me the light. As always, I am grateful for your advice

 

have you seen Pete Eastwood's thread on cowl steering?

Sprint cars have a modified 4 bar front end. It is a 3 bar. One bar only on the left side to eliminate the bind that a 4 bar will exhibit. So not really relevant to cowl steering with split bones. Cowl steering can be done if using a 4 bar front end.

 

Yeah you don't want Pete Eastwood to show you the light. It will be dim or turned off.

 

How come it works for the Rolling Bones cars?

 

Or does it ?..

 

Only one inch of suspension travel, that's how.

 

So I take it that I can make a bracket in the cowl and bolt it to heavy brackets on the frame?

 

Ha ha ha....and just like that cowl steering became taboo.

Make whatever bracing you need bolt directly to the frame. If the floor is sandwiched between the bracing and frame you're fine.

 

When everyone tells you it's a bad idea, and IT BUMP STEERS, why do you still want to do it?

 

They aren't called The Friendly Suggestions of Physics.

Mr. Eastwood is correct, and the rest of you who disagree are wrong.

 

Cowl steering can work. Whilst I agree that the geometry is never going to be perfect I have put many miles on my car and just returned from a European road trip of close to 1000 miles on varying quality of roads with no issues. Not sure how easy it is to see in the picture but here is my set up. A solid frame is built into the cowl and a plate that carries the mount is attached to it. The mount the other end is bolted through the floor/firewall.
There is a good tech article on the rolling bones set ups that we used ideas from here...

Just what you need in a cramped car...... A steering sector where your feet should be.

 

The box and shaft are above the pedals and the toe board. Don't know how big your feet are but I don't know many people that drive a hot rod with their feet up on the firewall.

 

Let it go..... There have already been post deleted... The thread will be next

 

Most I have seen have the subrail notched for the vertical support and then you hardly need to cut into the wood panel toe board to clear.

 

Yep, I read your missing post and it would probably still be there if you had omitted the 1st sentence.

You are correct...
