Most reasonable locker upgrade??

Hi guys. I have a 70 C20 that I'd like to have posi in the rear. It is a one legged tire burner that needs to burn more evenly.

It has a 14 bolt FF 4.10 rear but not posi or locked. Don't know ring gear size.

What would be the best bang for the buck to get both tires spinning while going straight? I know it should get new bearings and seals at the same time as the rear end has 300K miles on it.

Thanks in advance
