In the process of swapping in the S15 helical I ran into a problem removing the drive pinion shaft, companion flange and some of the associated races. The pinion shaft is pretty beat up and slightly bent. If anyone has a 95-96 open diff or these parts available I would be forever in debt to you. I have attached some pics if that helps. If all else fails I might be willing to take the entire open diff but I know shipping will burn like an STD.
