4L80E in 69 Camaro Shifter

[rdirgodwin]

I am planning a 4L80E swap into my 69 Camaro. I would like to use a factory shifter like the G6 shifter. I want the + - bump gear selections. I dont really like the paddle option. Does anyone know what shifter will work?
I also have a LS1 engine the car previously had a 6 speed manual in it. The harness for the motor does not have the auto transmission plugs for it. My shop is telling me to buy a complete new harness. This will allow the engine and transmission to work as one. Any one have any experience with these two problems??
