If for some reason I would like to convert my 2 wheel drive into 4 wheel drive wood places be there on my Jeep already for mounting parts. What I mean is like would there be a place for the transfer case with another front end go up under it fairly easy you know what I mean

 

It can be done. It is not overly complicated.

But it is not fairly easy to do.

There are tons of write ups on the internet. Alot of parts to source and buy. But the end result is a very capable machine. Dont be afraid of diving head first into the project
