Hey guys.. newbie 80 owner here. Here is a picture of my baby, she’s a 94’ with only 164000 mile.. center diff lock only. I have an opportunity to buy a 93‘ with lockers and 311000 miles. I’m thinking I’d could buy the 93’ and swap the axles onto my 94’. I looked at the 93‘ today, but it’s for sale through an auction and I wasn’t aloud to drive it around. I started it, checked all the fluids, backed it up about 50’, turned the diff lock switch but couldn’t get it to engage. It has a new radiator, radiator hoses and intake hoes. It ran great as far as I could tell, started right up and idled fine, AC worked etc. my question is, should I buy it? What are the chances that there is something wrong with the diff locks? Thanks!
