Wrecking yard 8.76

I just picked up a 1971 dodge truck 8.75 from a local yard for $450. It came with brakes and everything. I noticed one wheel wouldn’t turn when I bought but figured it was E brake or just seized from sitting in the weeds for god knows how many years. Long story short. I noticed that the brake drum is bent. Wondering what the chances are I have a bent housing. I’m new on here just finally building my 1970 duster I’ve had for 20 years. Specs on 8.75- 741 case with 3.23 gears from turning and counting
