It never ends. Leaky selector shaft seal.

Your problem looks like the lingage is flexing the shaft. Just look at the picture and you can see the shift linkage and the throttle pressure leavers are binding. I'll bet if you take the levers off the leak will stop.. Had one come here that was leaking. The lokar throttle pressure wasn't install properly.

The issue I see is that #1: the lug that fits into the lever isn't square with the lever and 2: there's no washer under that cotter.
I prefer washers under cotter pins because I've see the use of the 'thing' wear through the cotter pin at inopportune times. If you straighten up the angle of the dangle, you should be able to fit a washer on there.

Well just got to work, and my keys are not there, which means they are officially lost.

So pissed

My dad is Master Lock and Key in Longmont.....He's a cranky old bastard but he's knows what he's doing and he's SUPER particular. He's a also a Chevy guy, so pick your poison, but I bet he can impression a key and save you a buncha hassle.
