    Would like to see how you mounted the 40 ford rear radius rods in your car really looking for some laser cut brackets to mount them as well any one on the hamb doing them. Going to mount a set in my build and going to modify for strengthen as well. Thanks

    Do you mean splitting them and mounting them to brackets on the frame with a heim or tierod end? They will bind that way, I know it was done but...... Are you using a 40 axle? Check my build thread. 40 axle with 42-47 open drive center, bones and a Uniball. Works like its supposed to.

    No splitting using the rear radius rods from a 40 ford not the front thanks. Was looking for mounts if someone on the hamb was making and selling them .

    OK you got rear radius rods from a 40 Ford.
    Where do you want to put them?
    On the back axle? Of what? If so, what do you mean, not splitting?
    Or on the front of something?
    You are clear as mud, can't help so far.

    Imo the Hot Rod Works have one of the cleanest setups around for using the stock radius rods with an open drive banjo. A front radius rod mount kit and a torque arm kit to handle the torque. They are a H.A.M.B. Alliance Vendor...

    I know you meant the rears. Some guys used to either cut or heat and bend them to the outside of the frame rail when using an open drive axle.

    That's a nice looking setup for sure but at some point that little heim is going to reach its travel limit. If both wheels are moving up and down at the same time it's fine. When you go over bumps with the roads we all travel and one wheel is going up and the other going down that heim is gonna limit out pretty quick. The Uni Ball I used has 32 degrees of movement in any direction. Now granted, 32 degrees is over kill and my axle will never move that much but it will never bind either.

    NOTICE: 37-48 radius rods are not radius rods, they are triangulation brackets to keep the torque tube square. They are made from sheet metal and are nowhere near strong enough to control the acceleration torque or even the brake torque in the event of a panic stop. You should not be using these as locating arms for a rear axle..

    Let me first say that I know Mr Spadaro is correct and that the manner in which a lot of us, past and present, use them is not how they were intended. Just because people did in the past doesn't make it right.

    The last thing I want to do is question his vast knowledge. That would be foolish on my part.

    Having said that, I just wanted to say that my 37-48 rear bones are not what I would call sheet metal. True not more than 1/8" or so. Now the 1932 set we have in the shop, those are sheet metal. You could bend them over your knee. Still im not saying Mr. Spadaro isn't right, I know he's right.

    The underlined is the only thing SLIGHTLY questionable...and even if you do question it, the rest is dead on the money.
    The tubes ARE made from rolled metal...somewhat thick, but still sheetmetal by definition.

    There are also other problems with using JUST the arms than Mr Spadaro didn't bother to mention.

    I have a set to use...but will be doing a P&J/Rolling Bones style ladder bar with them as the lower link.

    Listen to ****. Here is a photo of the only way to use the stock 40 rear brackets. You can use them if you choose but they are not recommended. Good Luck.
