I got my dipstick tube from jeep4x4center. Com and had the same problem. My engines still in my car so I had to put the thing in sideways. It wouldn't fit past the bend since the material was slightly thicker than the original but I just filed it down and it worked. Also had to file down the ridges that are supposed to lock it in the block. No big deal if you know how to use a file and sandpaper. Easy fix
