Diff gear recommendations

Yoohoooo rabbithole.... @roccodart440 care to chime in about OD trans info? If I'm spending $$ on a TC, which could mean a trans upgrade due to mine being orig 67 904, then I'm willing to listen to OD "stuff".
Fyi, I don't want to do any tunnel mods/cutting.

All of you need to be spoiled someday by running an OD transmission.

You haven't lived until you've run 4.56 gears down the highway and only turn 2,500RPM @ 60mph.
