I've been looking at these on3 kits for my nnbs 4wd silverado. I called on3 the other day and talked to them about the modifications needed for this kit to fit on an nnbs. They specifically said the passenger strut tower causes major issues and a bit of modification. They did share the news that they currently have an nnbs kit designed and are doing testing and could be available as soon as the end of summer. They convinced me to hold off until the new kit is for sale.

 

yeah i had to cut and beat in alot of areas, plus cut and reweld the crossover.
