Sooooo Expensive learning mistake 
I bought a driveshaft off ebay thinking it was a one piece because I thought the "two piece was a 2 piece meaning it was two driveshafts with a carrier bearing.... Well today I pulled my old one and swapped in this one that I had referbed and balanced etc only to see that they are all one pieces but mine has the insert that I guess a 93 does not. Oh well It is fresh and balanced so I should be ok as I am only installing 3:55's but I was rather annoyed at my self for not knowing.
