Kenny Brown made one for the SN95s that will fit, i had them test fit one for me a few years back and the tech there claimed it would work no prob in a fox.
Snow Motorsports makes one as well, i believe its made out af aluminum.
I've been thinking about getting it but I don't know if it would really offer any rear advantages cause I already have a full MM rear suspension with panhard bar, HD torque arm, HD lowers, and coil overs. So for me I think it may be nothing more than a weight gain.
I have the Blue Oval Industries bar in my car. BTW, it was also on backorder, when I got mine more than 2 years ago. I think they simply drop ship it from the manufacturer, as I received mine in about 2 or 3 days! FWIW, there was no noticeable difference in handling, after installation, which was kind of a PITA!
You have to remove the covers, try and shove a pile of sound deadening insulation out of the way or judiciously cut it away, like I did. Next, put the bar in place and mark the holes. Remove your wheels, or risk drilling into your tires (they need to be removed anyway to bolt the bar in place, from the wheel wells). I threw out the cheap bolts that came with the kit, and went with grade 8 bolts and washers, I also had some alignment problems with the holes we drilled, so we slightly oversized them, out of necessity. I also painted the bolt heads in the wheel well black, so the zinc/gold plating would not stand out. I also cut the interior covers, so that they would go back on, with the bar going through them. I used a bit of fuel line, cut down the middle to neaten up the rough edges of the cut lines on the strut covers. (Make a note which cover is LH, which is RH, as they are slightly different, and the cuts are not symmetrical. I may speak from experience about this!) Very clean installation, overall.
Don't get me wrong, I am happy with the product and the results, but I could not feel any difference, whatsoever in handling. I installed a bar on an old VW Scirocco I had, and you could really feel the difference on the SOTP meter!
