don't replace front w/ polly right now unless have rust out shell or other problems.
Just install the huge rear rubber then drive for a while. That should stop cradle wander as you engine brake or accelerate.
Low mile car can have rust rot bushing shells or damage suspension otherwise & why car sat for decades.
Most tire shops & more do bare minimum of work & only see numbers on Bear etc alignment machine are good.
Even when suspension & alignment are perfect... the road & how you load a car can cause pulling etc.
Examples:
1. Many have roads have big crowns cause pulling to 1 side. If have 3 or more lane in one direction then left can pull left, Right pull right, middle(s) can go either or no pulling.
2. Old or high volume "Flat" roads can ruts cause pulling near random for what side & little or no warning.
● & both more so on any vehicle w/o power steering because non PS vehicle have < 2° Caster that make iffy roads even harder to drive on. Is why 84-87 Fiero has steering "stabilizers" attach to the rack. Normally you never know it there but hit a bump w/ 1 wheel or angled RR tracks & the stabilizer goes very stiff in microseconds so S-wheel won't slam you or worse.
3. Fiero GVWR = car weight + 2 x ~ 190lb people + ~ 50-100lb cargo. Have same or more weight in one spot then car can have steering, brake & other problems. But Even 100lb driver can affect wheel alignment on lighter cars & why some old shops can have the driver in the car doing alignment jobs.

So far so good, front bushing rubber out, a bit of a challenge, FYI. I did not want to use fire to get the center core out.
I used my soldering iron, slid it in gave it ten minutes then grabbed it with vice grips , turned it until it broke loose, then pulled it out. Worked great.
So grease, lube up the front cradle bushings before I put them in to keep water out ?
Is silicone grease acceptable?[This message has been edited by hunter29 (edited 06-25-2024).]

One more question, when I install the rear cradle bolts I assume I want to torque them to spec even if it risks breaking the nuts in the cradle frame , correct ? [This message has been edited by hunter29 (edited 06-25-2024).]

It happened to me on our '86 notchie, left side witch hat let go but on the disassembly. I would take the risk and torque it. If you get the "click" of happiness, you're golden. If it breaks, you have the opportunity to upgrade to a new unit as sold by Rodney and/or TFS OR a professionally home-built unit (like mine!) and satisfying results.

When I reinstall my cradle bolts, I chase all threads to make sure the bolts screw in with no resistance (from rust, crud), apply copious amounts of anti-seize... and yes, torque everything to spec (with minor allowances made due to the application of anti-seize).[This message has been edited by Patrick (edited 06-26-2024).]

Yes. It's one of those things that The Ogre likes to expand on when the use of anti-seize is mentioned.

Not yet... Wondering how much I should reduce the torque due to anti size, anyone ?

The Search function here works very well. 
Have a look at This thread. If you can't find what you need there, there are plenty of other pertinent threads.
