???Hi, I am new to this board but it looks like the right place for some answers. I would like to replace the 2F & 4 speed in my 82 fj40 with a 12B-T & H55 set up. But I have been told not to go this route but instead to use a 13b-t . The 12ht seems to be a twin to the 2f. So my question is will the 12h-t fit? No one will answer this for me and I am hoping that you guys will.
