Has anyone taken note of the direction, front to rear vs rear to front, of the bolts holding the IRS carrier in the frame? My mechanic buddy, noted to me, I had some bolts that would not come out once the sheet metal was installed. I have the trunk floor, with drop box installed. I am going to look at this further next trip to the barn. I thought I followed the instructions and previous builds, but could have just put them in the easiest way.
