Still no answer...

The rack shaft must be 375mm width...

Find only 487mm:

Please, anyone measure
offset length of the center link from the leftmost steering position to the rightmost

Where are you going to put a steering rack?

 

[1Slammed96SS]

No, It does not exist.

I know man, who made and completly installed this with about gmt 800 rack, BUT he removed and stay with stock.
He says: "Too long shafts rack". The steering rods with this rack have not correct angles. He cant find rack with 375mm shaft ...
All 3d model files are lost and do not have saved files....

Antbody have any ideas?

Still ask to measure centerlink offset length...

The geometry and spacing of the B-car (and D-car) frame and suspension, may, in theory, allow for a rack-&-pinion conversion. (See Ford Panther frame?)
That same geometry, however, will prevent the rack-&-pinion conversion from being a handling improvement over the recirculating balls steering we have now.
(It will also not be as sturdy as recirculating balls.)

That's the biggest reason why the past and present members of the ISSF have never bothered trying for rack-&-pinion.
If the threads prior to Aug 2009 were search-able, you'd find that the ISSF discussed it more than once, and with painstaking detail, determined (several times) that it's not worth the expense ... to us.
It MAY be worth it to YOU, though

Recirculating balls steering worked outstandingly for the '98-'03 (E39) BMW 535i, 540i, and the glorious M5 V8 sedans.

Sweet Mfg. makes a rack that will fit on the B-body. I believe the true distance between the inner tierod ends is 18 1/4" not 375 mm (14 3/4"). Sweet makes an 18 1/4", 17 1/4" and 16 1/4' racks in power and manual. They are not cheap. You can mount them different distances from the engine cradle to get the inner tierod ends to be in line with the lower bushing axes, for no bump steer.

Nice, I did not know that. I’ll stay quiet, but when Fred leaves I’ll be talking again. 🤣

According to Howe Racing, the tie rod spacing is 14.625" or about 372 mm, so an off the shelf rack that's going to fit in line with the original centerlink does not exist. Going further forward of this location makes the problem worse because the rest position of the tie rod ends is directly in line with the LCA bushing axis for bumpsteer reasons, requiring yet a narrower rack.

Only this kind/type steering rack most closer to "any 372mm" ) here does not matter ... 40mm or 372mm )

Daewoo nexia, opel kadett, opel vectra a, opel calibre a. have steering rack with hydraulic power steering lines.

That does not mean it fits properly between the tierod ends. It is going to give you major bump steer.

Besides likely turn in the wrong direction.

If I was obsessed with a rack in a B body full well knowing the amount the crossmember would be chopped up, I would be looking at splicing in a front crossmember from a car that already had a rack and arm geometry to suit it.

Crown Vic anyone ? ( been done )

Make a 4th gen F cradle bolt in the bottom while doing something different with the uppers.

Neither any harder than what is being proposed here.

 

[Fred Kiehl]

The Sweet rack would only require a bracket and bolts to hold it. It would fit in front of the crossmember. I am not sure how you would route the steering shaft, and that could be an issue.

The Crown Vic front end clamps with bolts onto the side rails, but the spacing might be a lot different, and the engine compartment may lose some space. It is a nice proven good performer for R&P steering. You still must route the steering shaft to the rack.

I work on cars with Sweet and Woodward racks.
I know how they mount .
A car that is going to be street driven in the elements for 10's of thousands of miles, meh not my choice.
Just the piggy back ram and the typicaly offset from center inner joints , not doin it for me.
You might also want to verify actual rack travel .
School buses turn sharper than some of the race cars in the shop.

Hey , please prove me wrong but I see this as all talk.

 

[Fred Kiehl]

You have more experience with them than I do, so you are right.

 

[95wagon]

No, I have more first hand experience with them so my opinion of them is based my experience with them.

The other thing to think about with a super narrow rack , the left and right bushes are very close to each other and are more subject to wear than a set up with a larger foot print.
Our old TA car I built had a Speedway Engineering Rack.
It was quite narrow with offset ends.
In short order as it wore it became a constant adjustment balancing act between slop and binding.
As you can appreciate , any inner end offset, if the rack rolls the joint height changes
I don't know if this stands true anymore but it was also explained to me by Frank Denny that a lot of this "stock car ish " stuff is never hardened for max wear resistance as they would rather see the stuff bend rather than break.

 

[95wagon]

Here are two retail companies ideas to solve the width issue .
These are 70-81 F but the set up would be nearly identical

Those center steer racks had enough trouble as I recall with wear .
Now lets pry away at those two inner mounting holes by putting that bar on there to relocate the inner pivots.
I find it hard to believe you would not see issues with keeping that bar shifting and the hardware not keeping it in place if you really drove the car hard.

This one they have addressed the rack shaft from rotating and killing the pinion by clamping a pair of rollers to the housing to guide the center link

Lot of stuff going on when a rack was supposed to have less parts and more direct action.
I really find it hard to believe this stuff if going to give a benefit over a racy dephi ( or a well done Saginaw 800) box ,
frame horn braces, and a precision idler and center link.

NOW , my comments above are opinion only as I have never used or tested the two above racks in anything.
I have removed a couple of HORRIFIC Mustang professional rack conversion kits that were same kind of deal .
Feel free to agree, disagree, comment.
You wont hurt my feelings .
