I have read, and re-read everything on here and maybe I'm missing it. The 7.5 with 3.73's in my BII is about shot. I found a ranger with the 8.8 and 456 gears at the junkyard. What all is involved? direct swap? I read about the explorer swap and understand the mods needed for that but am unclear about ranger to bII? Any help guys? Will the front axle be a direct bolt up as well?
