Recentering rear end in a 2wd Jimmy.

[skorpioskorpio]

I know the rear end in the Blazers and Jimmys is a bit off originally by about an inch from the actual center of the well. I need to place a bolt in notch and need to know where that is. The body and the frame are not in the same place at the moment so I was wondering from anyone that has done it where that lands relative to something on a 4wd frame (Wheel base, body mounts... but not cross members as my frame has none at the moment). The trailing arms are Porterbuilt tubulars so adjustment front to back on those is something that can be tweaked after but the notch is where it is.
