Default That's Not Good

On my way to work the other day, I decided to practice a little launch control a block from my office at a stop light.
Everything was good until I hit second gear and the rear end got weird, and then noisy.
Pulled into the parking lot and only noticed the passenger tire was leaning a bit. Looked under that side and did not really see anything wrong.
Limped it home (three miles) very slowly. Put it up on blocks and crawled under it to find this.
I already ordered the Van Steel bushing and reinforcement for it and will tear it apart when I get the parts.
Question: Do I have to remove the rear end to get the crossmember out?
I was hoping to just drop it down a couple of inches and support everything on jackstands and slide it out.
Can that be done?
Thanks.
Picture of what I am dealing with.

The rear end cover is bolted to the cross member from the top. I've done that job about a half a dozen times. Each time I had to remove the rear, I unbolt the other side, then lower the whole thing. Reassemble the rear to the cross member, then install it as one piece. It just happened to be easier. Iv'e tried different ways with no luck.

When you put it back together you can make or buy a kit which is basically a 4-5” diameter x 1/4” washer which will keep that from happening again.

Lower the whole assembly. Be sure to check the four bolts on top of the cross member that hold the differential. Years ago a few of mine became loose. One was not even hand tight! They were untouched from when they left the factory.

I know Van Steel sells them. They are around $40-50. I'm sure Ecklers or any other Corvette place sells them.

Pricey, but I think its better to do this job only once.
Cheers!

JKippin made a set for me, You can get some aluminum plate and machine them yourself if the prices are too high for you. THey really do make a difference. I had to special order the studs so getting a kit maybe easier in the long run.

heres an easier link, $40 bucks is pretty cheap though

Update.
Without too much effort, you can remove the rear crossmember without taking the rear end out of the car.
Getting it back in, may be another story.
Looks like all the tabs did not get bent over on the bushing install last time.
Oh well, live and learn.
