I think if it oil cans, it is a flat section, needs expansion not shrinking? Thoiught there are thise two flats towards the fron, each sid3e of the center crease.
To expand, back it with a dolly,and tap with a hammer directly on the dolly.
To shrink, you need an acetylene torch. Heat spot the size of a dime, and move on. No quench, no hammer, no big area. Just a series of spots.
Horror story- Unbeknownst to me, the original cab had 1/2" of bondo inside the roof. My nephew was running the samd blaster with orders that If he finds pink bondo, leave it. Oh no, he carves it all away. Inside the bondo it looked like somebody had used a digging pick on it. 1/2" pimples coming inwards, cattered evenly about. I've always thought it was a severe way of tightening up some oil cans.
