Haven't forgotten about you guys, just been very busy with work and school this semester :\
I've got a spacer bushing mocked up with Emachineshop.com and the price is pretty decent if we could get 2 complete rear-end sets worth ordered.
It's a nice unit with a groove to keep the rubber seal seated, vs. my previous design which unfortunately didn't the groove.
There is, however, another option. I found that QA1 makes a chromoly rod end, teflon lined, that is *almost* the exact width needed. By almost, I mean it's only 7 one hundredth's off what I measured from my factory control arm.
Here's a pic of the rod end:

The problem is, 7 one hundredth's isn't a small gap... but some sort of washer on each end would *work*, but it'd be a bit of a hassle to install. We'd also need to use a spacer (a very simple tube though) to take up the space between the bolt and rod end...
The first spacer bushing would be a lot nicer to work with, much quicker and easier to install in the car, and rod ends would be easily interchangable with other 3/4" units.
Any thoughts guys?
I've also got another product to use for the "bars" themselves that'll save a ton of weight, cut a lot of cost and fab time, and still be plenty strong enough to do the job. My friend that's building up his LNF powered Fiero showed me these bars, and he's going to be using them in a much higher stress application than our bars would be.
