I have a Nova 10 bolt one-legger in my '51 Chevy pickup as we speak. While it may "bolt in", you probably won't like it that way.

The stock spring center bolt is located forward of the stock axle centerline in the truck. I cut off the stock ugly Nova mounts from the rear end and welded on a set of standard axle pads AFTER I drilled a new hole in the pads to allow for the spring center bolt offset. Worked great...
