Rear suspension part missing

So, just got a great deal on a 93 Foxbody last week. Brought it home and was checking it out, I noticed a piece missing from both sides of the rear suspension. Can someone tell me what this part is and why it would be missing? Should it be missing? And, most of all, should I replace it? What's its purpose? I don't know much about the rear suspension on these, so hoping someone will have a good answer....

Those are your quad shock mounts. Most fox bodies had them. Basically, another pair of shocks mounted horizontally. Had a lot to do with preventing wheel hop but most say they're totally useless! The PO probably removed them when he installed the Koni's and never reinstalled them. You can leave them off if you choose.

I have had mine off for over 14 years, and replaced them with Strange 10 way adjustable drag shocks. I race my car, and have no traction issues or wheel hop whatsoever.

What control arms do you have? I removed mine with the stock arms
and it did start to hop on me so I put them back on.

Thanks for the feedback. That's good info.

I'm assuming these are stock control arms. Picture attached.

The prior owner also had 255/45ZR17 on 10x17 rims on the rear. Maybe a clearance issue.

Thanks

No those are actually aftermarket tubular lower control arms.When you step on the gas pedal and launch forward,the differential/axle housing will try to twist
in the opposite direction of tire rotation, which is to the rear.The quad shocks are placed semi horizontally to apply resistance to the housing,to help reduce this twisting motion.The upper/lower control arms also help with this plus they help locate the housing in the car.The stock control arm bushings are soft so this still allows the housing to twist somewhat.When you install control arms with stiffer bushings, it takes away alot of the twisting,which allows you to remove the quad shocks. When the stock arms are still in place,the quad shocks are helpful because of the deflection.

Stock replacements are good. Parts stores call them steering dampeners. I'll have to do some googling because I can't remember the part #. I think it's like 14337 or so... But they are $25ea and work well.
Wheel-hop is power related. But not having them on there if they aren't "needed" always seemed kinda silly to me. There's no negative having them, sometimes people HAVE to remove them because their wheels are too wide and rub. If the wheels aren't rubbing and the one removes them what do they gain, a seven pound weight reduction?
