can i get a rear end from.....

well I have a pair of spring perches that I can weld on from the dodge dealer ....and I have experience with putting a B-body rear in an A- body by cutting the perches of and welding a few inches in ...don't remember the measurements now....but I was just wondering if a jeep or Durango was even close. like a C- body rear, its just not even in the ball park so no go.

and what bolt pattern would a jeep or Durango have ? do they have five or six lugs ?
