Aftermarket TOBs squeak / squeal because they have ****ty bearings inside...that's why they don't last.
The squealing is usually caused because the TOB is slightly touching on the feelers of the clutch causing the TOB to spin and squeal.
The spring like the ldcchicago piece (which didn't work for my 98) push the TOB off of the feelers. That way, the TOB is not spinning or moving at all so it doesn't make noise.
This should make the TOB last longer as well since there's no unnecessary spinning.
What I did with mine was to place two springs from under the stock seats hooked one to another and attach to the clutch cable and then to the opposite end to pull the TOB back.
It adds very little effort since the springs are very light, but is enough to pull the TOB off the feelers. I simply hooked them against the metal that's under there. The springs grab and hold w/out falling off believe it or not. I need to take some pics when I'm under there next. I've had them off a couple of times and put them back on and they hold fine just catching on the metal.
You can actually hear a little chirp when you first press the clutch in which lets you know that the TOB just made contact and hasn't been rubbing.
I also use the Steeda clutch pedal adjuster to get the slop out of the pedal. I have the UPR firewall adjuster and triple hook quadrant, so it's set in the middle of the hook to get the pedal close to the floor.
Hope this makes sense....

It's similar to this, but I used two springs because they came from under my stock seats and I just hooked it to the metal of the tranny, not a seperate add-on piece.
