Advice on potential gear swap

Definitely think 2.94 is gonna work best for my application now. Again, just want to make sure this swap is going to be as simple as just changing out ring/pinion, new gasket/fluid, etc without having to modify anything else (new TC with different stall, modifying shift linkage, etc).
Don't forget to change your speedometer drive gear.
