) I then tore down my 23 spline case with the 4.7 gears so i could convert it to top shift. I got the rails all clearanced and installed, reassembled today. Also swapped the rear driveline flange on the case so my new CV rear driveline will bolt up when i get those built. Pretty stoked to have that done! Tomorrow i'm gonna tear down my donor 23 spline to use for the crawl box. My adaptor should be here wednesday

I have never seen a 23 spline input shaft before and was amazed at how much larger they really are! They have alot deeper splines on them too. Here is a pic for reference (23 spline in the background)
Also another pic of the 23 spline 4.7 case all reassembled with the top shift setup.
