Tech Tips:-
* All JIMS Super Kits require a # JM-8042K Speedo Sensor Block-Off Plate Kit. If the speedometer is not driven from the transmission, then two block off plates kits are required.
* All JIMS 6-speed installations require the speedometer be recalibrated. For calibration kits use Dakota Part # DAK-SIM-1
* The JIMS Trap Door extends 3/8in. farther to the right than the stock part. Alterations to some parts that attach to or around the trap door may be required.
* JIMS Spout Spacer # JM-8088 or SS56-1292 will be required on FL’s and spout may need modification. OR require the LH trapdoor ear to be machined off so the oil filler spout can bolt back on.
