Here are the part #'s you need to get your front end back on track!

This is just to get me through till I get the brackets made. The difference in height is 3/8" so I made a shim to accomplish this.

How are the frong sway bar bushings with shims holding up?

They don't...it didn't work out. I had a set of the shims too and even with them it would take less than a week to twist the crap out of the brackets. By two weeks the brackets were pulling over the bolts. They just aren't strong enough to take the load. I'm pretty sure Rrdstarr has gone back to the factory brackets too; I sure hope so! We had a club member break one of those ES brackets on the road and having one break or pull off the bolt under cornering load could lead to a mess. I ended up installing zerks into my factory brackets and put the ES bushings in. That was months ago and they are working fine. The non greaseable bushings in that same size and shape can also be used and should work fine too. I also did some grinding to the little lip at the end of the factory bracket to make installation easier.
