I've been shopping for a Montero, and trying to find a decent one. I found a 97 LS that I like, but its an LS.

I'm not 100% sure in the difference between the SR and the LS? I know it doesnt have a locking diff, but how hard is it to swap out? What else is different? I do like the cloth seats in the LS's and I take it the LS wont have heated seats? Any other differences?

Any tips or thoughts.

Thanks guys
Scott
