Put mine in what a difference,one of my favorite mods, in canada $260 total but worth it,very easy install.

I finally got around to installing mine today. I can confirm that the bolts are M8x50MMx1.50 thread. I got four of flange bolts from Lowes for $3.62/pr.

As for the install...as mentioned previously...it'* straightforward. Just used a 15mm socket for the strut bolts and a 12mm socket for the bolts. I ended up pulling up on the right bracket after I installed it so the bar would clear the alternator. I now have about 1/4" clearance over the alternator. I also pulled up the the left bracket to make it symetrical. I also put a little bit of blue threadlocker on the bolts. That'* just me.

As for the test drive, it seemed to actually make a difference. The steering felt more solid and the car felt alittle more confident on the off ramps.

5/26/06 EDIT: I also recommend gettting longer strut tower bolts to compensate for the bracket thickness. Get 6 M10X20mm X1.50 thread (Grade 10.9). I got six of them from Lowes.

Actually, the correct bar bolts are M8 50MM x 1.25 pitch thread.

I finally got around to changing those out today.....thanks for the reminder......the longer strut tower bolts to compensate for the bracket thickness. Used 6 M10X20mm X1.50 thread (Grade 12.9) Allen Head capscrews.

I was surprised to see that the original bolts were only grabbing about two threads.

9*for some reason the gm dealership in mississauga, ont charges about 180 bucks for the bar and the brackets are 40 bucks each, i'm not about to pay almost 300 big ones for a piece of pipe and 2 brackets, i happen to own a welder, and i can bed pipe also, little bit of fab work i'm sure one could make this in a few hours with right tools and know how, all for the cost of a case of beer and half a saturday......... i'll post some pics when i make my own

has anyone ever tried this on a Park Avenue??

I have a 1998 Park Avenue now as a winter driver/second car & thought about adding one...

The 97-05 P/A is slightly different than the G, H, K & Ksp bodies in some aspects I've come to find out! :?
