I cant tell you exactly how wide it is, at least not now - im out of town. But i can tell you it will work fine on your truck.
Here's one under my '55.2 Task Force truck. It is very close to the width of my former chevy 10 bolt and the stock rearend. I dont think i'm going this wide but the guy that is says I will be able to put a 315mm wide rear tire without tubbing the bed. I doubt I'll go bigger than a 295. Anyway, hope this helps:
