Default 84-87 front suspension

I have a 1986 front suspension and am trying to set up the sway bar, but am missing the bracket that mounts to the lower control arm.
Help!
Thanks

You want to buy one or to know how it fits?

Both. looks like the lower control arm has two holes in it to mount a bracket. The frame builder just attached the swaybar link to a hole that doesnt look too strong. I pulled up a diagram and noticed that a bracket attaches there to shift the stress to two different points. I like the early c4 set up and forged upper and lower arms, but want to set up the sway bar the way it was meant to attach.

They removed the entire lower control arm top bracket where the shock and sway bar mount. They have the QA1 coilover mounted to a smaller bracket in the bottom valley of the control arm then the sway bar just mounted to a factory hole on the side of the control arm. Not optimal...

Not even adequate in my opinion - passing the load of the sway bar to just one pressure point on one arm of the control arm. I think you'd wind up with a broken control arm after a hard bump...

They may have done that for clearance with the coilovers

He's my rod end setup if it helps

Here's a coil-over on an early model that looks like it used all the original hardware correctly:

yep...they took the "shock plate" out so the coil-over would fit. The coil-over makes the shock plate useless...so if you go back to conventional shocks and the monospring, you gotta have that plate. Look around FleaBay for the plate. I was just looking at some while seraching for new control arms to polish & swap out with my plain aluminum arms..not so pretty.
ANyway, its just the shock plate ...bolts on, sway bar end link set bolts to that. Not a big deal. Get a drawing and its pretty self explainatory.

Here's a set of control arms with the shock mounting plate, sway-bar links and the sway-bar link attached.

Here is an identical setup as mine:

and

You can see the new lower shock mount, but the sway bar mount is gone now. I don't want to connect it to the hole on the one leg.
