Most likely would. Besides, it's steel and involves completely removing the stock mount so you can adjust things as needed. I'm betting it will be very close otherwise.
Another option is the NTK ones, although they aren't on sale. They are listed for FJ, 4Runner and Tacoma, all the same part. So the AP is likely to be the same and they just haven't realized it or tested it yet.
