I searched but couldn't find anything on this subject. I came across a rear diff with 4:11's and a Torsen Posi from a 4th Gen Camaro. Other then the axle splines being different, will this work with my 79's rear diff? I can get different axles if needed.

The year of the F body is important. 3rd gen F bodies (which were 1982-1992) the early ones - up until 87 IIRC used a 26 spline setups. The later ones went to 28 spline.

G bodies are 26 spline. I used a 84 Trans Am carrier with a factory Auburn posi. It bolted right in perfectly, been running this way for at least 6 months, no problem.
