Help! Grand Wagoneer owners!?

[francis higgins]

I know this is the wrong forum, I'm sorry. I posted this on the Jeep side too, but I'm concerned that it doesn't get as much traffic. I'm looking at a 91 GW. It is a very nice vehicle. Convince me to buy it. What problems/limitations should I be aware of or look out for. How reliable/sturdy are the 4-wheel drive systems (especially the vacuum operated hubs(?)). Does anybody know of the possibility of adapting a Chrysler 4-speed auto (it already has a 727 and AMC 360)? Any opinions/info would be greatly appreciated. I looking to make a decision ASAP. Thanks in advance for your input!
