Technical F100 steering boxes

I'm doing a 29 tudor with flathead, "A" frame, 33 unsplit wishbone. I'd like to see how some of you that used F100 boxes mounted your boxes. Thanks

 

I'm interested to .

 

Just did a search. There's a lot of info on it. I can't transfer it but hope it helps.
Do a search in the tech archives also.

 

check out the tardell book on building an AV8 its worth its weight in gold!

 

Try Mel Gross at melmodela@aol.com or (714) 292-8660. Mel reworks these boxes to bolt into the stock Model A without cutting anything and look like they belong there. Remember that some of these early truck boxes had the steering shaft above the sector shaft and some below and this affects your steering box clearance with the exhaust manifold on the V8 but the problem doesn't exist with the stock 4 cylinder.

You mentioned F100, but search F-1 as well as there is a lot of info on that mod as well.

I believe they work better, more compact.

 

I think the F1 is the same size as the F100 but this may be the design that puts the sector shaft above (or below?) the worm gear. Definitely something to check out.

I don't have it in front of me, but Tardell's steering box book says the F-1 are smaller than F-100. Or maybe later F-100 are larger?

 

The mounting flange is not at 90 deg. to the sector shaft. but speedway sells a wedge plate a 1957 pitman arm will except a standard tie rod end.

 

F1 boxes have the column shaft come in under the steering box, F100's have the column shaft come in over the steering box.

F1 boxes are sometimes a better fit when trying to make exhaust/starter/steering fit into a compact space.
F100 boxes provide a better column angle for your steering wheel. Less vertical.

As far as I know, they are roughly the same size.

 

Speedy is right the two boxes are almost identical in physical size it's just the steering shaft placement that differs , often with an F1 box you wil need a universal to get the column at a suitable angle. I think the F1 box may use a car type pitman arm as opposed to F100 clamp style with the through bolt.

what he said. I have a one of each in the garage.

 

Yes, you're right. I forgot to mention that.

Vern Tardel's steering book will not only answer your questions about suitability of the various boxes, it will also tell you how to inspect, evaluate, repair, modify, and service them -- a worthwhile tome for your old-Ford hot-rod library.

Hey Mike, Does the latest version of the Bishop/Tardel book have the measurement corrections in it? I have one of the older versions with the old measurements. Just wondering...

 

He has a separate book just on steering boxes.

 

I know, I was referring to the Bishop/Tardel book "How to build a traditional hotrod" not the Tardel "Let me show you how" manuals...

 

That's what I figured. Check this:

Thanks for all the replies. Sounds like I need to get that book, also sounds like I need to find another box. This one turns real smooth, I thought I had a good one to use, there's just not much room.

 

Also, how cool is it that Mike Bishop replied to this thread, I was a huge fan of American Rodder, still mourning its demise.

 

Thanks for this

 

Richard, thanks for that link, some very interesting stuff. I bought a 33 wishbone, sounds like I may have to make some modifications to it. Thanks for everyones help.
