Its going between a 4 speed and a split case out an 87 FJ60 so thats 19 spline, right?. I got the 4.7's in it too
ya, I just had Marlin build this one for me so it has the spring. I didnt have a top shift t case lying around so I splurged for once
I use those in all of my mini truck dual case builds. It should be included in all kits.
