Ok, so the saginaw 3 speed transmission that came with my 72 blazer is a big piece of sh#$. Anyway, all i needed was a new mainshaft, and I could only find ones for a 2wd saginaw. In my long quest to find any info, just wanted to let you all know that the part number for this is WT301-2c. It is 13" long. I cannot find this part anywhere and this is what i need. Anybody got any ideas. Everywhere I call doesn't have one and has no idea where to find one.
