Driveshaft

So i bought my niner front driveshaft free. I'm guessing because the VC was shot but I never got a chance to test that theory. New t-case went in when I replaced the trans. Got a new driveshaft from a new friend on the forum and tossed it in.

The bolts that hold the axle end of the driveshaft are as tight as I can make them with a ratchet but they aren't putting any compression on the linked washers. I'm guessing thats not normal. My assumption is that as the po ran without the DS for what looks like a while it is just rusted at the end of the threads and wont go in. Should I just pull them and soak it in pb blaster or wd-40 and try again? How much vibration is acceptable when the DS goes in? It vibes a little more and doesn't want to move in idle anymore. Should I pop the diff cover and check the gears?

Any and all help appreciated, the 96 has a bad steering box, so I need this one running.

Maybe different bolt lengths and you are bottomed out? Maybe someone can chime in and tell you if there are different bolt lengths depending on driveshaft type. That would be my guess.

The bolts were fresh off my 96, but thats a reasonable bet. Maybe I'll put the shaft on the 96 and see what happens? Once I swap the steering box of course.
