1G End Case broken

[1990TSIAWDTALON]

Since I am new I have to post this in the newbie section. What kind of fix is there for a broken end case on the 5 speed in a 1990 Talon AWD? This one has a crack probably 6 inches long and yes the nut had backed off of the 5th gear shaft. Lotsa, "goodies" in the bottom of the end case but luckily nothing got into the gear set, just a broken 5th gear syncro, wave spring and syncro dogs. Chime in with your own fixes or what the best couse of action would be. I am pretty well acquainted with gear boxes so maybe just finding another end case is the only true, good fix. I'm open to all comments. Thanks.

The only fix is to replace the end cover after re-torquing the 5th gear nut.

Thanks. Good answer to a stupid question. Are they available?

Does anyone know why a nut that is torqued to 107ft/lbs and staked come loose?
