bellhousings

["Joel M Brodsky" <jmbrodsky@xxxxxxxxxxxx>]

Binders,
      I have a bellhousing, clutch, and throwout set from a Trans that I
never saw.  So, my questions are these:
Does the V8 bellhousing differ from the 4cyl, by the 4  transmission bolts
being offset by about 20 degrees?
Can a bellhousing from a T18 go onto a T19, and vice versa?
Are the Dana 18 and Dana 20 Bull gears the same?
What is the low ratio for a Dana 18 Transfer case?

Thanks!
