    OK, check this out. Thinking I have a U-joint issue on hand through the grumble and gring sounds, I figured I have a week and get to it on Satyrday coming to do a swap out of the pair. There OE equipment from the '78 donor car .... it's time.

    I jack up the Magnum, chok the wheels, slide in a stand, lay down the cardboard behind the bumper and swing on in. I get to about the rears pumpkin and noticed..................

    Left /drivers axle Rear Shackle U-Plate ripped, inside, the outside

    Passenger side inside, pass. outside, a pair of shots.

    OK, thats the bad news. I called up a buddy in the "Been there done that!" deparment in Ct. state. He also owns one of these late B bodies. I told him I found this part from Auto Rust Technicians in Rhode Island. But it was listed for F/M/J cars. According to autrust guys, it'll work, but not being to OK with the way the convo went, I figured a quick call would help.

    My bud confirmed it would but the Poly biscuts would be a tad to thick. They sandwhich the spring for ride comfort dampening road feel making the ride a little smoother. He thinks there a tad shorter in length.

    I don't know how I'm going to "MILL" the biscut down for a better fit? :rolling:
    How do you thin down a poly brick. There rectangle. Something like 2 wide, 5 - 6 long, half inch or so thick.

    Well, there ordered and coming. Stay tuned.

    Heres the site; http://www.autorust.com/k_40.html
    Theres the picture. I was told there zinc coated.... I think.

    Glad you caught it before they went COMPLETELY. Thankfully, fixing it is not terribly difficult.

    It is ethier an attempt with FMJ parts or swap it out for a older 8-3/4. (Which wouldn't be hurting my feelings, just the wallet.)
