I put the 9" in the Rampage because it was for DW and
at first I thought about changing rear gears for the
daily drive.. easy drop out the center and put a road
gear in.. then I changed my mine for the 518 OD.. so
glad I did... but the 9" will be under it with a 4.10
gear for now... I might make a gear change later
EDIT
For the Mopar purist.. the 8 3/4 IS a true mopar rear
end.. designed and made in a Chrysler plant.. as
was some of the smaller rears with the stamped housing
