I don't know if this part helps with sideways movement or not.....but it was there.
It is shown in cvxjet's posted picture.

Oh, you mean that plastic shield that helps to keep heat off the battery. I thought you were referring to a plastic tray that sits under the battery, like a tub.

I have one similar to this in my Subaru.

I can grab my battery and shake the whole car.....I suspect Monkeybean does not have the right battery.

A heat shield made out of plastic? That would be a surprise. I think they wanted to trap the power cables away from belts and pulleys, and prevent battery movement sideways......but who knows.

The plastic "Wall" to the left of the battery is double-walled so it definitely is for heat protection.....It has air flow up thru it to help dissipate the heat from the engine.

For sure. The picture in your earlier post shows this quite well.

Yes, Fiero/GM battery trays lock both sides of battery base.
And won't move "sideways" related to the "clamps" points either when have right size and type of battery and tray is in good shape.

It helps to install a battery make sure:
metal "clamp ear" is good and no crap stuck under.
Put battery in and push into the metal ear.
Put plastic block and bolt in but don't final torque the bolt. (some cars let you to pull/install battery w/o completely removing these parts but easier to remove most times. Plus can clean etc the bolt at same time.)
Find/make a "wedge" or tool to push the block tight to the battery.
then torque the bolt.

There is no "torque spec" for mounting hardware in FSM.
Needs careful tightening so won't move but don't go so tight plastic warps etc.

Also OE bolt is made for this job w/ most have a big thick captive washer.
The washer is so big it hinds most to all of the slot in the plastic block and even a lot of block too.

Many are missing the OE bolt and block won't hold right w/o the big washer to spread out the loads.
If missing just go to junk yard and get some bolts w/ blocks. GM use same mounting on Millions of vehicles so shouldn't be hard to find.

Closeup of mounting hardware.
Is Not a "self-threaded" bolt tho looks like one. Just so fools won't strip the parts.
Plastic block doesn't mater which way up. Can be easier w/ smooth side up because washer may have trouble adjusting to battery case.




Bat Tray can rust out for 2 main reasons...
Salt in winter or live near Ocean.
Battery/Alt had problems and acid leaked out.
Can have either or both.
If you think had acid leaking... Must check/fix frame and plumbing under it. Hard Brake line & T under there and Fuel line(s) depending on Year.

Can any BCI group 75 battery be properly secured with the Fiero clamp setup?

Or does one have to be careful in selecting among the available group 75 batteries for one with bottom lips of just the right size?
