At 6½ inches of lift we knew we were going to need a slip-yoke-eliminator. So, we picked up regular-length kit from JB Conversions for just $199. With the distance the Comanche has between the rear axle and the T-case there is no need for a super-short kit. Plus, the ’91-only speedometer sender and speedometer won’t work with the sensor and tone ring in the super-short kits. We opted for a 1350 U-joint yoke at both the T-case and rear axle and went with a Tom Wood’s driveshaft to connect the two. The junkyard front driveshaft worked great. Just make sure you grab the driveshaft from an XJ or MJ with the same transmission and T-case you are using to avoid any length problems.
