OOP's explained to out well. I did duals behind my auto using two gear drive cases for the simple reason I can have a 4.70 gear set for the back case, which is the prefered method. Oh yeah of course I used all Marlin parts.
As a side note, still waiting to see if someone comes out with a "box for rocks" type reduction box using a chain drive t-case planetary like they do on Jeeps. Maybe then we could find something to do with all those chain drive cases we're replacing. Chain drive cases have a little lower reduction that gear drives, IIRC.
