Your problem is that you're trying to use the 2.5 pick up tube on the 3L windage tray. You will need to use the 2.5 windage tray to mount the pickup tube properly with the OEM hardware and brackets.
To mount the 2.5 windage tray, you will have to change the location of one or more of the outer main cradle studs so that the holes of the 2.5 windage tray line up correctly. Remember that these are TTY one time use bolts that should be replaced.
