I have Atlas 2 tcase I bought new few years ago, its the newer heavyduty gear design. I have 2 different Input setups for it I have 25spline 5bolt for Ranger and Explorers that use 1350, 1354 tcases and then also have 31spline front input with 6bolt pattern like what bolts on back of V8 explorers auto tranny. Im trying to clean garage of a few things, this was 2500 new and the extra input setup was like 300-400 i think. Will sell for $1500 firm cash, will not ship. Also it is 4.3 -1 low, has the heavyduty spline count on front output shaft.
