I recently did a motor swap for a friend in his 99 wj. as payment he bought me all my beer and food for the weekend and whatever parts off the parts truck i needed. i recently been having problems with my transfer case so i decided to take the np242 out of the 99 wj. i have a 88 xj with a np242 with a hack and tap installed on it. knowing that my jeep is so old i have my speed censer on the tail housing of the rear output shaft on my tcase. on the 99 wj tcase its a more modern electrical connection on it. i was wondering if i just switched my tail housing onto the newer tcase to allow my speedo cable to work, would that work? im assuming the 242 in a xj and wj are the same cause they both have a 4.0 with a aw4 trans, but we all know what happens when we assume. also would my shift linkage be the same too? the wj had a diffrent type of stick to put it in and out of 4wd.
