Hello everyone, new member, here.
 

As the title says, I'm new here, just joined. By the end of this week, I'll be getting a 1989 Isuzu Trooper. It's pretty much stock and in fairly good condition. I noted, from the under-hood accessories plate that it didn't come with the LSD rear differential so, installing a locker is high on my to do list. From what I've read, this Trooper came with a 12 bolt rear diff. How can I check and verify the rear diff model? Thanks for any info and since this is my first Trooper, I'll surely be asking more questions.
