For my 2 at the pumpkins i used 4, 3/4 bolts like set screws drilled and tapped threw my shield, then made 4 divets in the pinion snout on the diff housing( just drilled a tiny bit so the 3/4 bolts wouldnt walk off and let the shield slide). Run them down tight and i have a nut and lock washer inside the shield to snug the bolt up to the shield so it dont loosen. Then my other 2 i fabbed brackets up to the bed cross members. I didnt put on in the front transfer case u joint yet cause of the limited space. Ill toy with that this year. If i can remeber to take the camera to the garage ill snap a few while im puting the new one piece rear shaft in tonight.
