Basically all the suspension is in stock place minus the shocks. You have to run coil overs. You have to cut the shock tower out of it. I'll get some pics up as soon as I can. Minitubbing it doesn't affect the gas tank at all. I'm a body man by trade, and like challenges! But to be honest, anybody with common sense could minitub a mustang.What I'm sayin is, it really wasn't that hard , all your really doing is removing the wheel tub. I didn't buy a kit, I just fabricated everything. Come out pretty damn good.If your willing to do it , let me know I'll give you a hand.
