GM discontinued axle stopper bushing?? Well rear end was scrapin c6 19's on acceleration so figure time for new shocks. I take the rear shock off and see that the shock is in good condition and actually stiffer then the GR-2 shocks I had purchased to replace them. So I put them back but then saw the springs might be the issue. I could compress the spring some with my hand! So needing an immediate fix I had to choice but to buy some stock replacements from parts store. I then see the bushing thats goes between the wheel well and the top of the axle is ripped in half. Advance, autozone and bennetts doesnt sell them, and I call the pontiac dealer and they say discontinued. What the hell do I do??

Find a better dealer or buy online.
GM part number 10164173
Oh and BTW....
That part is commonly called a bump stop.
Compressing a shock by hand will not give a real indication of how "stiff" it is. You may be able to tell if it is degassed but no way are you going to be able to compress it quickly enough to get a feel for the valving.
You should be able to squeeze the stock springs a bit by hand. They're only ~115 lb/in.

the bump stops are on National backorder. I found a few dealers in the region that had one, but nobody that had a pair. ended up buying some used ones from a guy on here.

Hmm ok taking ur advice about the shocks and trying the gr-2 shocks. the spring I just got to replace the stock one are atleast 50% stiffer so going to just use them. I called the idiots back at the dealer and gave them the part number and they pulled it right up. PS found them on gmpartsdirect.com for $21 vs dealer $36.
Do you think its ok to drive the car without them ? untill they come in that is

what gm parts direct is not telling you, at least not yet, is the parts are unavailable. I ordered less then a week ago, then I called to check status and was told there not available. it took a couple of emails to cancel my order.

A non-sponsor has some bump stop replacements with a bracket that allows you to use the generic bump stops found at Autozone, Advance, etc.
Not sure if they're a sponsor here though.
You are correct sir, they are not a sponsor

Those are fine except that they give you the same problems as the SS bumpstops....
1) (Apparently) taller than the Z28 stops = less suspension travel
2) Less travel = you're into the stops more frequently (and you're already into them about every time you drive the car even in normal conditions)
3) Poly is MUCH harder than the Z28 foam rubber type = a much more abrupt and unsettling impact when you get into the stop
Even if 1 and 2 don't apply, 3 is enough of a reason for me to stick with the factory part.
Can you physically drive the car? Sure.
Are you at risk of damaging a shock with no bumpstop? Yes.

Oh, and I owe you an email, Ironhead. Had to address a few things on the other car lately that have kept me from having fun with the f-body.

I wasn't aware of any difference/problems with the SS bumpstops. Guess I have some reading to catch up on. Could trimming them help with the difference in suspension travel, or would it be pretty much pointless? I knew poly was stiffer, but wasn't sure how it would do in such an area.

The SS stops are like this. They are hard rubber formed into basically a blunt rectangle. The Z28 (and I guess V6) stops are softer foam rubber fashioned into a much more progressive pyramid shape.
Email away. I believe I PMed you my address a while back.

Trimming the bumpstop would actually make it harder since it effectively increases the rate by making it more blunt.
