Your grandfather's tires look like they stuck out about as far as mine did when I had my old 33"x10.5" KOs. If you really want skinny, typically going metric is your best bet but that means going to a 16" or 17" tire...meaning you would need to buy new tires after getting brand new KO2s so that's clearly not a realistic option unless you were willing to wait till they wore out. Otherwise you could also buy replacement flares, wouldn't be surprised if you could find a like new used set on Craigslist. That way you gain back the coverage you lost and have less tire beyond the flare. You have a lot of considering to do.
On the Toyota: That thing will probably run forever. Personally I love Toyotas, was looking at them when I was looking for my Jeep. We've got a 2004 Tundra 4WD Limited that we've had since new (140k miles with not a single problem), a 2015 Tundra TRD Pro, and my old ride a 1971 FJ40 (had a Chevy 350 so not technically a true Toyota), and I have to say that little truck looks awesome. Of coarse I would do a SFA swap and maybe drop in a newer Toyota motor for giggles. That all being said, I'll be the guy to say walk away. The truck looks in great shape for a great price but it'll end up being distraction from what you have already got going on with your other toys including your TJ. Once you drive the Toyota, you'll start wanting to modify it and that's money you could spend elsewhere on the Jeeps. Just my pitch on it, awesome truck though.
