Rear diff question

Is the 7 1/4 a really weak unit? If you are on a budget, why not try to break it? You could still put the spring relocation kit on to prep for wider wheels while saving a few bucks or sell the falcon diff. I dont see any traction on your ride right now. I think its a cool car for sure! I personally like the challenge of breaking ****. If you cant break it, no need to swap it. Do the 7 1/4 have the "lunchbox locker" available? Really cool car though. Has that Mad Max look, especially with the Arizona background.
That is in oatman as lol
