J-Nut on lower control arms for front shock lower bolts

    Does anyone know a source for the J-nuts pictured? I don't know if they're original, but they're perfect for attaching the front shocks to the lower control arms. Unlike others you don't have to remove them to get the shock in and out. I've had to resort to Home Depot for a generic and lighter-duty version of these (U-nut barrel rather than U-nut with a captured nut), but I'd really like to get a box of the J-nuts pictured.

    One hint is that the stampings on this J-nut are "<T> 5618" and "100-130". I believe "<T>" is the manufacturer and "5618" is the style, as searching for "5618" results in very similar J-nuts, but they're for thinner metal than our lower control arms which are 3/16" thick at this location.

    I see that Inline Tube sells a kit called "(C-7-10) Inline Tube Front Shock Hardware Mounting Hardware with Insulators Compatible with 1964-77 A-Body Chevelle, GTO, 442 and GS" that includes these J-nuts.

    The 1970 Factory assembly manual page 3-4.1, revision July 1969, shows this J-Nut as
    PN 391359, NUT, 5/16-18 NC J-Nut; NUT, shock absorber

    I have a buddy sending me some. Thank you for you offer Brian.

    I was hoping that someone had found a source, like Auveco, for a box of 25 or so.

    Put anti sieze on the bolts! Really helps

    Here's what I found a Home Depot, for about one dollar each. They work OK, as you'll have to install them after installing the shock absorber as, unlike the originals, they don't leave enough room for the shock to 'slide by' them.

    Anti-seize on the bolts is a good idea too. Thanks John.

    Brian, I'm not sure how much the new ones that you have from Inline tube cost?

    AMK B-13235 appears to be a better fitting version of what Home Depot sells, at twice the price (two for $4). It's listed as for GM Shocks too.

    AMK B-10615 appears closest to our originals, although the thread size is slightly larger at 3/8-16 (instead of 5/16-18 ). At four for $3 the cost is going in the right direction too.

    Mike,
    You have a set of 4 originals going your way. Price, free, and thanks for the parts you sent me.

    I do carry the AMK versions if anyone else reading this is in need of this fastener (OR just about any other Fasteners that our Buicks require)

    Sorry Todd. I should of remembered you have the fasteners. All the stuff I have gotten from you has been great. Got to order the '70 heater hose bracket next.

    "Speed-Nuts" are another term for these. Have taken quite a few good ones off clean southwestern cars in the yards (while they were still in the yards)
