Got the shift linkage hooked up. I read conflicting information on whether the stock linkage would work or not. When I had the pivot bracket in the factory location, it was binding and would not allow me to drop the shift lever past R. So I moved the bracket forward one bolt hole, and drilled a new hole in the frame for the forward bolt.

Now, counting the 'clicks' I can drop it all the way down to 1 if I wanted to without issue.
Toughest thing was drilling at a bit of an angle. New drill bits but they kept wanting to walk on me. So I used my dremel to make a small divot first, then a 1/4" bit to start the hole, then 3/8" bit to finish.
