Is my rear end too shotty?

That title is funny I dont care who you are....

I am in no way technical so please excuse my termonology I have no idea what these technical terms are.

I bought a '69 - 12 bolt rearend with 373 gears off craigslist and think I may have made a bad purchase. I opened up it up AFTER purchasing it ($100) and found that it has not had any lub in it for MANY years. The gears were all rusted up and stuck together and inside the bell housing and down the axel tubes are rusted up too. I took it to a local radiator repair shop to have them "Dip" it. $60 later I find the gears are pitted and inside the housing is still a rusty color and there is some grim still in the housing and down the axel tubes.

I then took it to my sandblasting guy and he said he should be able to clean it up pretty good but he has to be really careful where the bearings go. He said he can mask that off.

Is this safe? Would I have any problems in the future is I go this route?

I plan on buying new gears, I have already purchased an axel rebuilt kit since I was installing a posi, which is already purchased. Id like to use this housing just not sure if its salvageable.

Any imput would be greatly appreciated!!
