[Short 3/4]

I agree that you would probably be happier leaving the front 4:10 and changing the rear to match. I went from 4:56 to 4:10 several years ago on mine and am very happy with the change, works great both on and off road.

I would disagree though for the need to swap the entire rear to do it though. I was able to find a doaner pumpkin with the right ratio for a good price. Is a very easy swap. Despite what others may say if you keep it full of clean oil (just like any diff) it will outlive you. I’ve been using HO’s HARD for 40 years and never had a problem, or seen anybody else have any either.

Just my opinion. Whatever you do have fun with that cool and rare old truck.
