Another vote for Spectre premium. A few months ago I installed one in my 99 4runner. It fit great and appeared to be as good as stock. I bought it from Rockauto, and the first one came with one of the radiator line nipples bent due to the packaging, so they sent me a replacement the next day.
Just reading your post, it may not be so jerky and sway side to side if you put your sway bar back on and possibly replace sway bar bushings and end links.
There is an o-ring gasket on the distributor which most likely needs replacing. The distributor needs to be removed to do this. There are write ups on this forum how to do this.
I did try sliding the topper windows, but there isn't any slack in them and I am trying really not to break anything. I will try a slim jim today after work.
I have an 85 4runner and I locked my keys in it. They are sitting on the seat on the key ring with other keys. I have been trying a wedge and a bent coathanger but with the flat lock/unlock button there is nothing to grab onto. any tricks or suggestions would be helpful.
