think i need a longer driveshaft..

[sickomode]

hi everyone i need some advice/help! 2000 3.0 5spd. swapped in a 8.8 4.11 limited slip rear end, and installed f31 deaver 10 leaf pck. everything went smooth until a few months of part time daily driving when my driveshaft started slipping out. added a pinion angle and went to buckle everything up again, but it doesnt line up right and rear end looks way too far forward. i have a heavy duty alum driveshaft that is 45.5 inches, and ive come to the conclusion that i might need a longer one. its way too far off for a spacer of any kind, and i dont want it to keep happening, but im also not quite certain if thats it of if im just having a brain fart? if anyone has any input that would be really appreciated!

Not sure what might be going on, that sounds like the length of the driveshaft on my '90, yours isn't a long bed is it? If anything my driveshaft is too long as it bottomed out from axle wrap before I added a traction bar...
