I have an 83 d100 with the 4 speed 2wd but am looking to 5 speed swap in a trans I got free from a 93 dakota 4x4. My issue is I want to keep the 83 d100 2wd, I have the t-case from the dakota but it's blown. I don't know what I need to make it happen so any advice/part numbers would be helpful. I have the drive shaft from the dakota too.
