Needing driveshaft for a 1985 Mercedes 300cd?

[o2guy500]

Hello, this is my first post but I really enjoy all the informative information on here. I removed my driveshaft before knowing that is was factory balanced and cannot for the life of me get it back together right. So I'm just going to replace the driveshaft and need to know if there are any sites online that are recommended? I don't have any local shops that I can find so I'm guessing my only option is a remanufactured online driveshaft. I live in Eastern,Ky so if anyone knows somehere close that sells them or online I would greatly appreciate the info. 1985 300cd
Thanks, Kelly
I think I may have posted this earlier in the wrong forum so sorry for the confusion.
