    I have a 1940 rear axle. What is needed to mount the model T spring?

    Take the remains of the stock bushing out of the spring and use a new shackle pin/bushing. The real parts houses sell many different sizes. You can either find the proper size for a 40 Ford and add some collars to take up the slack of the narrower spring, or maybe get lucky and find pins that will fit the spring and then can narrow the rear's hangers a touch.

    The wheel base will look odd with the '40 axle housings moving things forward. Mice period way it the Isky Roadster setup with the housings swapped left to right, right to left this makes for a longer and much more pleasing look. Bob

    If you mount the spring behind the axle you may have a problem of the axle bottoming out on the frame. Do some rough setting up before you get too far into things.
