Default Driveshaft install

So this spring/summer I finally got around to putting the 9" in. I'm by no means a mechanic, but I do my best to try and do things on my own. I really wish I just paid to have the rear installed, but I was replacing the fuel pump while the rear was off. Nothing seems to just slide into place and bolt up[ like it's supposed to....most due probably to installer inexperience. So I finally have it all in with the final piece waiting to go in.....the driveshaft.

It's hard to get a straight angle into the trans because the driveshaft angles up and through the safety loop. The driveshaft goes into the trans about an inch, then stops. Even trying to get it back out of the trans I have to tug at it. Everything seems to say the driveshaft should mostly effortlessly slide in, so what am I doing wrong?

Make sure it's going in the spines.
Usually much easier if you put the trans in gear so the tail shaft won't spin, then wiggle the driveshaft back and forth while pushing in.
Should be distinctive when you feel it slide in.

It's hard to get a good straight angle into the trans with the driveshaft being angled up into and through the safety loop.

Loosen the loop, wiggle the shaft, grease the splines (so it slides easier).

I've always used the grease for input spines (during clutch install) but I imagine most will work.
You don't need much.
