Brake pads are done.
Nothing really. Basically just work on improving the tune and drive it as much as possible to check reliability. Have to find a trailer that I can borrow that she’ll fit on. My neighbor says I can borrow his but I am waiting for his son to get back from utah so I can measure it.
I would like to have a cage and rear bumper/tire carrier built but that’s just not gonna happen in this heat. Should get that stuff done this fall when it cools off.
So, my Blazer will fit on my neighbors trailer if I put on stock rollers... is what it is I guess.
That front driveshaft sure seems short. A lot of spline showing. You could probably add 3" to it, more spline engagement.
And you still have some time, if you are going to add length to the DS, why not move the axle forward some while you're at it?
If you haven't already...

AND if you move it forward, it will help with that CV angle. 
It’s showing alot of spline but it’s a 12” spline. Lots of engagement still. The axle is already 2.5 inches forward. And when the dana 60 goes in it’ll push the shaft back about an inch.
Good question. Lol. I know the spring will come up and hit the grease zerk fitting on the drag link. I need to space down the bumpstops so it doesn’t do that. As far as droop, It is good with gravity droop but I need to throw some limiting straps on it so it doesn’t stop on the shock when forced farther.
So this is gravity.
This is where the strap stops.
Done
I measured the amount of shock shaft showing before I hooked up the strap, and then after. With the weight stretching it I only lost a 1/4”. I guess that should work.

Haha. It’s only single shear mounted ya know...
I don't like that driveshaft...
I thought my old one was good, never had a problem. One day I was hitting this obstacle, trying to climb rock slabs. The front passenger wheel slipped off the rock while sliding down backwards. The wheel drooped that side as I slide backwards, grabbed hold of something while still barely on the gas, and pulled the driveshaft apart. Luckily it didn't hurt the splines bad. Was able to file the ends enough to slide it back together.
Twisting the truck up just doesn't tell the whole story some times.
I have a slip similar to yours but at ride height I'm only showing maybe 2" of spline. I'd have to go measure.

Would this work as some extra insurance untill I get the 60 in there?
This is what it looked like on the ground BEFORE I moved the axle forward 1-1/2”.
I agree with @K85 Octane about the trail causing situations where the driveshaft could separate. I've experienced the same problems and that's why I run a 12" slip now.
With the strap installed I would go find a place to twist the suspension up stuffing the driver front with the passenger front fully drooped out. Mark the shaft, then pull it apart to see how much spline you have engaged. Most driveline shops will want you to have at least 3" engaged and you probably want to add an inch for trail scenarios mentioned above where axle wrap and various suspension movements compound the issue.
