DW - Death Wobble - Trac-Bar Bracket Question

Purchased used, lifted TJ - 99 4 cyl. I've had it a while now, over a year. Rarely drive it on the road. Recently, I replaced the clutch etc. First time I took it on the road after replacing the clutch, I got horrible Death Wobble. Figured it had something to do with the clutch replacement, but I haven't seen anything wrong. Since that first Wobble it was ok the few short trips I took on pavement (less than 3 miles).
I had to get it smogged, 20 miles, fine until I got to town, hit a bump in the road and got the horrible Death Wobble again. 4 more times while I was in town, then nothing all the way home.
I've been searching the internet and most of the time the Death Wobble seems to be caused by something worn out in the front suspension, usually the Trac-bar bushings.
I did a dry turn test, looking at the trac-bar closely. It looks like the person that put the lift on, also added a trac-bar bracket extension. The entire extension bracket pivots around the bracket mounting bolt. It moves a lot. There is a second hole in the bracket that looks like a second mount location but there doesn't appear to be a hole in the Jeep bracket to put a bolt through.
So, very long question just a little shorter, should this mounting bracket extension have a second hole with bolt to keep it from pivoting? How about the stabilizer, looks like it may have been leaking (oily dust covered).
Also, I put some new (used) tires in the back recently, had them balanced, but could that be doing this?
Thanks in advance,
Paul

Put the track bar back into the stock hole and ditch that bracket.

Ditch the bracket and use an adjustable track bar to center the axle.

X 2 on ditching the bracket.If you have a 3-4" lift,you need to drill another hole near the stock one.Make sure the front toe is set to 1/8" (alignment).Unevenly worn or impropery balanced tires can cause it also.I've only had DW twice and both times it was just because I lifted the Jeep and didn't align the front immediately.It takes 10 minutes to do it yourself.

Thanks guys - definitely going to ditch the bracket, but each of you had different advice on what to do after that.
1. Put the trac-bar back in the original bracket. (will it fit my lifted Jeep?)
2. Purchase an adjustable trac-bar - (Ebay?) Adjust it to fit the two end holes, or is this used to center the axel? How?
3. Drill a new hole close to the original hole. (How do I know where to drill, wherever it lines up?)

Got advice on how to center the axel?

I'm an old guy (58), and fix everything myself, but I haven't worked on front ends much.
Great link to the toe in. One of the first things I had to do to this Jeep was replace a broken front axel it had when I bought it but I never checked the toe in.

How my much lift do you have? If you're not sure, measure the springs from where they seat on the axle to where they seat on upper rubber coil isolator.

Options 2 & 3 will center the axle.Here's the least expensive way I've used on 7 of my 8 Jeeps.Stock hole bottom left.

Even with the bolt tight, it can still happen...
