1988 YJ transfer case
Hi folks, im new to tall this forum stuff and jeeps. Here is my issue. I have a 1988 Jeep YJ 4.2L 5 speed. The transfer cas got busted my previous owner, so i found one on kijiji to replace it with. It has all the same numbers marks ect other than serial number is diff, But the input shaft on the new one i have is an 1/8" smaller than the orignal one that came off it. Does anyone know why this is? its off the exact same jeep i seen it. Im stuck with this one now and not sure what to do. Im looking for info and or how to tell things apart, any help would be greatly appreciated i know very little about jeeps. Thanks for your time!
