Greetings All,

I am hoping that someone out there in T land would share the wall thickness of the front radius rod tube. I am not finding that info anywhere and don't want to cut one open to measure it. Thanks in advance, Bill

I have cut a few of them apart for various reasons and repairs. What I know. The thickness varies from front to back, thicker in the back if I remember correctly.
Earlier type over-the-axle wishbones are thinner material than the under-the-axle wishbones. The early ones therefore bend easily, which contributes to their notorious instability.
The common later type also seem to vary somewhat in thickness. I do not know if specific changes were made over the years or what? Maybe one of our esteemed researchers can enlighten us on this. Maybe tomorrow in the daylight I can find a few of my wishbone pieces in the parts piles and get a quick measure.
If a quick guess would help quicker? I would guess the variation to be above and below about 3/16 inch thick. But don't count too heavily on my failing memory.
Drive carefully, and enjoy, W2

The 1916 drawing calls for the tubing to be 1/8" thick. This was continued from at least the year before. There were slight changes being made almost constantly; I have that information in the complete set of the Releases and will try to look it up. The Ford script was added in May of '16, FWIW.

I have a cut wishbone in the stash, looks like the 1920-25 style. It measures 0.15" or 5/32" thick at the cut near the ball in the rear.

Thank you all for your input and your time. This is just what I needed. Bill
