Wow, cruise, push-button 4wd, but crank windows, and is that just a radio (no cassette deck)? It's always seemed to me like power windows and locks were all but mandatory as soon as you started adding options; could be wrong, could be this one's the exception, or maybe it was a special order. Looks pretty straight. I remember when I was a kid some family friends had one (I think a '91, maybe '92) with that same pattern on the seats. If I come across a really nice set, I'll probably nab them for old times' sake. I'm guessing I'd be very lucky to find any that nice, but it's not like what I've got is trashed.
I'm also planning on running 31s, and I've got 3.73 axles. I don't know how optimum the combination will be; at least it's kind of in the middle, and I'm hoping for decent gas mileage without killing all the get-up. I'd guess for heavy off-roading, you'd want 4.10s all the way, but 3.55 would be better for highway driving.
