    The "must have" braces are to connect the upper-front trailing arm bolt to the lower-front trailing arm bolt.
    The upper arms pull so hard on the crossmember, they can destroy it. These braces can help reduce that pull. UMI 4028 is for 68 and up. UMI 4029 is for 65-67 a-body.
    Don't leave home without'em.
    The only braces I have used that attach to the rear shock, are the ones that allow lowering the back end of the rear trailing arms for traction improvement.
    I removed them and got TA no-hop bars that raise the rear of the upper trailing arms.

    Those braces are the UMI version of the factory big black tie bar braces.

    My factory braces are stamped steel and show signs of stretch. I'm replacing them with UMI braces just to be extra safe from disaster.

    Gary, as of to date what rear shocks are you using ? Also are you using the UMI rear shock tower brace ? Thx John.
