used transfer case and actuator
 

hello
my ride is a 2003 4.7L v8 limited. i have been enjoying my 4r since 2014. unfortunately my ride is stuck in 4Lo. i am searching for a used low mileage transfer case with actuator. i am new to searching. i have noticed there are more used v6 transfer cases with actuator than v8. i want to know if generation 4 v6 and v8 transfer cases with actuator are interchangeable. i know replacement costly. my ride is worth it. if any of you have knowledge on this subject please join in. thanks.
