Another source for a Ford F-150 OD transmission is Sheridan's Repair in Nunica, Michigan. Call Tim Sheridan at 616-836-6477. His is a "drop in"
tansmission, not a kit, that does not require any cutting of the center cross member. Tim has made and sold his conversion for a number of years. I purchased and installed one earlier this year and am quite pleased with it. Tim explained to me that there are 3 different OD ratios that Ford offered with these transmissions and I strongly recommend that if you purchase one get the OD gear ratio that best suits your engine and your normal driving conditions. If you live in hilly or mountain region you would not want the highest OD gear ratio available as it could result in lugging your engine too much. Sheridan transmission conversions use the standard Model A bell housing.
