I am in the process of building brackets that will allow me to run toyota calipers and rotors in the rear of my FJ62 and have toyed with the idea of using a wilwood mechanical spot caliper for my e-brake and just incorporate the mount into the bracket I am making. I am not sure how well its going to work, so I would like to know if anyone has had any luck mounting a fj40 output shaft drum style e-brake on a FJ62 t-case.
