Its not long Enough to come thru the throttle body at all.. Do these studs come out?

The side that isn't broken is all jacked up too. I guess the washer and bolt when assembled (not sure what it's called) won't stay in place.
I'm not sure about the studs. Try looking in the back - maybe use an inspection mirror - and see if there are threads there that the studs are mounted in. In short, try to figure out how the studs are anchored.

As suggested, you might try unscrewing them with vise-grips. If you break the studs off, you can try drilling them out. If you try that, stuff some rags in the throttle body opening so that shavings do not get down in there.

That said, if you break the studs off, maybe the next step is to go to the junk yard and look for another plenum.

In brief, try to get a close look at the studs - front and back - to see how they're attached and see if you can get them out.

There's a hole in the back of the broken stud on the left not the right. There's just no room to do anything back there lol

Well... The studs do in fact screw in and out. I used the 2 Nut Method and a little PB to get the other stud out and it worked. Now I'll bring it to home depot and see if I can find the same stud size thickness. Moving right along folks! Thanks everyone! More updates to follow. ?

The idea of looking in the back was just to see if there were actually threads there versus something else such as splines.

Good news on getting them out! Kudos on using the two nut trick :)

As for finding replacements, you may need to go to a mom-n-pop hardware store or even a specialty shop such as Fastenal. You want fasteners that are plated (to avoid rusting). Also, the long-and-skinny shape might be a challenge.

You may need to find a bolt of the appropriate length, then cut off the head. Not sure whether to orient the cut end out, or put it in the threaded hole. My first thought was to put a dab of epoxy (eg, JB Weld) in the hole, then screw it in. That would glue it in place as well as seal the cut end of the bolt. But there may be some better reason to flip it around that I haven't thought of yet.

If you can't get your hands on anything that's suitable, you may need to go mail-order. Try www.mcmaster.com .

Good luck finishing it. Don't forget to pick up a new throttle body gasket.

Thank you so much! You wouldn't happen to know what the other part is called? I have searched high and low online but I just can't think of what it would be called... You've been super helpful and I really appreciate it ?

Other part? I'm not sure which one you're talking about. One of these in the pic?

It looks to me like you have all the pieces - just need some bolts (studs). If one of the flange nuts is stripped and needs replacing, you can use a regular nut and washer. You might consider going to a junk yard for the fasteners, including the studs. See what you can get there before looking too hard elsewhere.

Take the nuts with you for the 2-nut trick, or get a reverse torx socket that fits the studs.

Also, in addition to McMaster-Carr, if you have a Grainger nearby, you can get parts shipped into their stores for free (if it's not already in stock there).

All fixed! The next day I went to UPullAndPay and looked for 2006 and newer impala. To my luck I found an 08 LT. I removed the throttle body and took the studs and the Grey washers (not sure what they're called) out and brought them home. I may have also removed some other parts from the car that I wanted lol. Long story short I was able to replace exactly what was broken for 6$ and now she's back to normal. Next project is the creaking noise and the radiator fans! Thanks again everyone!
