I swear I had good intentions..........
The crossbar on my transfer case had some play in it and I wanted to tighten it up. I took the crossbar out, and drilled out the holes in the shift rails for bigger pins. However, when I tried to drill out the crossbar, it is so hard it actually ground down my drill bit. So now, the holes in my shift rails are 3/8", and the crossbar holes are 5/16".
So my options are to disassemble my transfer case and track down some other stock rails, or twin stick it. I'm leaning towards twin sticks.
