Ford 9" rearend, how complicated??

[UATahoe]

Found a ford 9" rearend that was installed on an 84 chevy pickup. Has new wilwood disc brakes, 3.73 gears, and posi.

I am needing to completely rebuild my 2.73 open carrier rearend with drum brakes. I am swapping in a 383 motor and was going to move to a 3.73 gear and posi. Eventually want rear disc brakes as well.

Price is 1250 for the Ford 9". Not sure how firm but it would have to be lower for me to consider. Was just curious if this would be a good bet rather than rebuilding mine, or if rebuilding mine would be the best way to go? I am guessing it will bolt right up.
