Steering box from a IROC/GTA with 16" wheels. For those who don't know it has stops that allow for wider front wheels. I had 245/45/17's in front and no rubbing when turning at full lock. Same performance ratio as the MCSS and I assume TR boxes, 12.7 to 1. I had this in my 86' Monte for about 15 years, 20-25k miles, in good working shape. I splurged for a Lee box so this is now available, just removed this past weekend. Kept the pitman arm for my new box. $100 shipped in the US.
