Hang tight, I'll find the thread for you.
Replace that thing before it falls through all the way. It's not nice when you're driving and that happens.
In other words, don't drive it except to maybe move it in the driveway.
We did luck out in that we didn't have to replace the rack or anything other than the subframe. But my son's car being an ATX, it was a royal pita.
Edit: I can't find the thread where I talked about it but the basic story was that my son's 93 ATX broke the entire rear section of the ear off and it dropped down to about 4" off the ground....while he was driving. He was fortunate that he was only going about 10mph. When the tow truck arrived we couldn't straighten the wheels so it could be put on the flatbed so he lifted the front of the car up with the bed of the truck. It took both my son and me to turn the wheel straight, that's how much pressure was on the rack. But it didn't need to be replaced. We were very lucky there.
When we got it home (after the $110 tow bill) we found that both sides had actually broken. Finding a good ATX subframe up here in MI is difficult but .... (.......) came through and fabbed up an uber reinforced subframe along with hockey puck bushings and braces. Bill Saunders came over to our house and helped to get it replaced. My son's car wasn't too bad to work on but compared to MTX cars, the ATX is a real pain the ****. (IMO)
I could walk you through it with no problem, it's really about the same as replacing a clutch with the supporting of the motor and dropping of the subframe. Just doing it on your back can be just lovely (NOT!) if you have a gravel driveway like we do.
One item of suggestion for you. When you find a replacement subframe, be sure to give it, as well as the tops of the aluminum subframe bushings a good coat of spray paint where they mate up to cut down on the natural corrosion that happens from the contact between the two.
