[QUOTE="LV_Ford_Fan, post: 16852262, member: 145523"] This was written as a guide for anyone planning on making a Magnum swap. It's just a list and not a how-to since I have not done the swap yet. I have looked at many threads here, YouTube videos, and other things to put this together. I want to stay with facts and not opinions and not mention any vendors by name. There are three Magnum models for our cars: TUET-11010 - Ratios 2.66 1.78 1.30 1.00 .80 .63 TUET-11011 - Ratios 2.97 2.07 1.43 1.00 .74 .50 TUET-16884 - Ratios 2.97 2.07 1.43 1.00 .80 .63 Note: Some vendors offer swap kits which include the transmission and one or more parts mentioned below. The Input shaft is 26 spline so a 26 spline clutch disk is required. The Output shaft is 31 spline so a 31 spline yoke is required. The Magnum is longer that stock so the stock driveshaft needs to be shortened or a custom driveshaft is needed. Remember the 31 spine yoke requirement. The Magnum does not quite fit the stock crossmember so the crossmember needs to be modified or an aftermarket crossmember needs to be used. The wiring harness will fit but not in the stock location so zip ties can be used to secure it. There are pigtails available to modify the wiring if so desired. There may be some interference with the Magnum shifter area so the tunnel can be modified or low profile shifter bolts can be used. There may be some interference with the case prongs that protect the switch on the right front area of the case. You can see on the stock transmission these have been shaved down. Some people have shaved down the Magnum case and some have used a hammer on the tunnel to make room. This is reported to be a small amount. Reports have shown that the stock shifter handle does not work well with the Magnum but there are aftermarket handles that have been adapted. There are aftermarket complete shifters available. Complete shifters for the stock T-56 won't work. The Magnum mechanical speedometer hole comes with a rubber plug. There are aftermarket metal plugs available. There are reports of a missing hole for the clutch dust cover bolt. There are reports of the clutch fork needing to be ground down to clear the case for taller clutch configurations. Let me know if I missed anything on my list. Remember I am trying to stay with facts and not opinions. [/QUOTE]
