Looking for some voices of experience... got a CJ on Rockwells and 49's, 401/T18. Have a short output Dana 300 sitting in the garage. Should I build the 300 up with input and output upgrades and run with it, or just bite the bullet and go with an Atlas? I am pretty easy on the skinny pedal, and this Jeep is just a crawler. Hate to spend a couple grand more than I have to....thoughts?
