Ok, got the trans mounted up in the car.
I did use the shift lever from the 60. Also used the bracket on the original shift cable to mount to the new trans. I did have to oblong the holes in the bracket to get it to fit the 80, and also had to slightly bend the bracket toward the rear of the car to take up a little slack in the cable, but everything looks pretty good.
I have NOT shifted the car using the shifter (car is up on a lift with tons of other things being done right now), but will let everyone know once it comes down....I don't imagine it'll be a problem.
In the meantime, anybody have any pics of 4L80e trans cooler and/or cooler lines with a turbo build? Trying to set mine up now.

Okay, I just looked through the post.. I have to ask.. Why the black silicone between the pan and the trans case? PLEASE, PLEASE do not do that in the future. If GM did not use silicone-YOU do not need to use silicone! Gluing the pan to the trans case simply means that if you ever need to drop the pan you will PERMANENTLY DAMAGE & DISTORT the pan trying to get it off. Also, if ANY of that silicone is on the inside of the pan, it can break free and get into the filter... Again... Leave the silicone OUT of the equation.
Glad you guys are finding such good deals on used, running, transmissions. I am paying upwards of $350 PER CORE for 4L80E's and all of them have to be completely torn down, hard parts replaced, parts machined, and completely rebuilt, before installation.

Okay, GM did not use silicone on your trans pan when it left the factory. Do you guys that glue your pans also put silicone on your engine oil filters when you change your oil? How about on Fel Pro oil pan gaskets? How about intake manifold gaskets? It makes as much sense to use silicone on those engine seals, as it does on your trans pan.
I build on average 15 transmissions a week. I don't use silicone on any transmission pan gasket. I do not have problems with trans. pan leaks on any unit leaving my shop. The only issues we have with pans... are when we have to pry them off the case because some jack-wad used silicone on BOTH sides of a perfectly good gasket. So, let me rephrase-PLEASE, for the mental health of your transmission builder-leave the silicone in the tube where it belongs. If you never plan on servicing your trans, or rebuilding it-then continue gluing them on if that makes you happy.

Gm also didn't dual feed the directs. Do we really need to do everything exactly the same as the general?
I mean...I agree, I never use silicone and I never have issues on the units I build...but using GM as the be all end all of mechanical reasoning probably won't fly
