I am in need of a PCM F0TF it's a power train control module for a 91 Ford F-250 4x4 automatic transmission with the E40D and the 460cid engine this PCM has is discontinued by ford and was put in E and F series 250 to 350 as long as it had the ,460. Interchange years is 1989 to 1994 my truck is broke down without it and I can't seem to find one anywhere
