what $$ is a complete 8 3/4 worth?

Not many mopar swap meets up here. Rear was adversised in a local buy sell trade book called Uncle Henrys. I called 1 st thing and told them I was on my way. Nothing fancy, stock small bolt axles, undesirable cone posi, small drum rear. Needs upgrading for some serious power. I would think w the upgrades on your rear, it would be worth at least $1200
