Last year I was rebuilding a salvage and had to replace that rear qtr. There are many pieces to it. Before I decided to sell the project I was looking into just replacing the whole tub. Used tubs are around $1000-1200 back when I looked. All the new mopar replacement panels are darn close to that if it got into floor etc
Go to car-part.com which is an online directory for salvage yards. Search for "rear clip". That is what they classify the tub as on a JK.
