    lower rear spring plates

    Would someone have in your bone pile, a pair of lower rear spring plates, Ford basic number 5758, 5759 for a 3 inch tube rear differential?  Maybe older Ford car or light truck that used a 3-inch tube diff.  These are the ones that the rear shock attaches to.  I would send a picture of the ones I took off my '65, but I don't know how to do it.  Thanks

    Re: lower rear spring plates

    For consideration - I used the original Mustang spring plates and elongated the holes to fit the 3” housing.  I then made a ¼” plate to fit the 3” housing and mounted it underneath the spring plate.   
    Note that some older Ford cars had narrower width leaf springs than the 2.5” wide springs found on the Mustang.

    Re: lower rear spring plates

    You can order new from Mustang Vendors or, I used my original 66 plates and slotted the holes. I then welded thick washers underneath to strengthen the slotted area.
    All that said, I think I might have one side in my pile.  I can check…

    Re: lower rear spring plates

    I checked today. The plates I have are all for 2-3/4” axles.   Sorry but I can’t help this time.

    Re: lower rear spring plates

    I have purchased parts from this guy several years ago.
    He was reasonable with his prices.

    I found him on Craigslist at the time, but I believe he has a FB marketplace account now.

    Minnesota as I recall.

    He is closing his doors soon, aka retiring.
    He has Ford and Mercury parts from 50’s to 90’s.

    I said I was retiring.  Never said I was “old”.

    With you being 67, you didn't have to tell us you were old.  We can always say we've got the mind of a twenty year old with decades of experience.

    Re: lower rear spring plates

    I installed a 9" rear axle that was custom made and it had 3" tubes. I took a pair of 65 spring plates and had the holes welded shut. I then re-drilled the plates to fit the custom bent U- bolts that fit the 3" tubes.

    Overall, that is probably the beet way yo go, IF you can drill through part weldment and part mild steel without the bit walking toward the softer metal. Get it right, as I am sure Ron’s competent hands did,  and you have a perfect fix.

    Thanks MS for the complement - but I have to admit that I did the mod back when I was still working for the airline. I gave the welder and a machinist a dozen donuts each to help me get the holes filled and the plates drilled. :-) Worked like a charm....

    Re: lower rear spring plates

    Clamped on a mill table and drilled with an end mill solves the "walking" problem.

    Thank goodness for machinists at work, the guys I dealt with liked different flavored coffee beans.  At one point, they had me get them some "Jamaican Rum" flavored beans, after delivery, then told me there is alcohol in it and were reporting me to security … thankfully they were joking. (However, I didn’t buy it again, and checked the label on whatever they did ask for!)
