Desperate need of urgent help regarding u joint

Hey guys, I posted yesterday regarding needing a new driveshaft. Well, long story short, it is just the front u joint and I am in the middle of doing it myself. I am following this video- https://m.youtube.com/watch?v=oUjkc8KsJAs

The only difference is at the front end his drive shaft just slid out. Mine has 4 bolts (unlike his) and I'm wondering if that is what is holding it on. Is it because mine is a 4wd? Or does that make a difference? I will post a pic.

yes the 4wd's use a fixed flange type of front joint and have a center slip joint just aft of the center u joint.
