Front driveshaft to short ?

I am pretty sure my front driveshaft is to short. Will I need to have one made or will a driveshaft from another vehicle work?

4.5 RE lift with 2inch Pucks = roughly 6 to 6.5 inch of lift.

Currently I am running the stock driveshaft any valid thoughts would be great

many people get away with the stock shaft at that height....

the AW4 is about an inch longer than the 5 speeds, so the front shaft from those would be even shorter which won't help you. possibly the shaft from one with the 2.5l, but I would suspect those would be shorter as well.

you won't need a new shaft though, you can get yours retubed longer, usually $50-100. I did my own, but I have a D44 with lockouts so the shaft isn't spinning in 2wd, when I do have it spinning in 4wd I don't get vibrations until 35mph.
