    Differences between OBS and SD 7.3s?

    Does anyone know of a post on here or a different forum that goes over the differences between late OBS motors and PMR motors? I’ve looked and looked but haven’t found anything worth any value.

    Zf6 swap question

    Ok so I found a decent deal on a zf6 with a transfer case and both drive shafts. It came out of a RCLB super duty and I'd be putting it in my RCLB obs. Question is, are the drive shaft lengths close enough to work? I searched every where and didn't find anything about the shafts.

    obs serpetine belt

    Dumb question, is the tensioner on obs trucks turned by a torx bit? I know the superdutys are turned by a half inch drive and I figured my truck would be too. Seems like the torx would be easily stripped out
