well this is probably a dumbass question, and I'm 99% sure I know the answer. but, from outside I can't fully make sure I wanted to see if anyone could tell me for sure before I start the work. this part I picture that holds the front coil and shock on my 10th gen 2wd F-150, I've heard similar parts doing the same job called a couple names such as coil tower, and seen them replaced with available new parts on the OBS fords. but, I've searched looking to replace mine if possible, and I can find no part name or part number anywhere including ford OEM, nor a replacement part. so I've convinced myself this must be an integral part of the frame on these trucks, and I'm stuck with the ones I have, correct?
