I also will say that I have always liked Suzuki products. They are like Japanese VW's well to me anyway.
I just picked up a 1988 Samurai soft top with 64000 miles. It has the following mods that I know of(i did not get much info from the PO).
Spring over axle
3" body lift
4" suspension lift
Diamond plate front steel buper
Tubular steel rear bumper
Front and rear hitches
Drive shafts extenders
So everything seems to work well. It runs very good has great power for the size of the motor and runs smooth.
It has a bad front end shimmy...steering wheel just wobbles pretty bad.
The diff housings have a small rubber hose coming out the top that goes no where?? What is that??? Is this a vent? A line for vaccume line for lockers?
Any info about this truck would be helpfull.
Some of that steering shimmy might be caused by bumpsteer as you mentioned you had a Z-link style draglink. See the following article at Ack's FAQ:

at Ack's FAQ for links to bumpsteer solutions, too.
Check to see if the differential input flange on the front axle is parallel to the front output flange on the transfer case. You can use a magnetic angle locator - available at most hardware stores along with Home Depot and Lowes.
The angles should be exactly the same on both flanges. If not, you probably have an out-of-spec. Caster angle that will cause steering problems. The PO created this problem not being aware that pointing the differential upwards to the transfer case changes the front axle's caster angle AND creates driveshaft vibrations. Do a search for driveshaft
for several articles including Driveline Basics with Steve Johnson
and Tom Wood's Driveline Geometry 101
Even though Consumer's Reports accusations that Samurais are unsafe
are so much BS (a whole 'nother topic), It is always a sensible idea to keep any modified vehicle's center of Gravity as low as possible. That said, you might consider removing the 3 inch body lift. I have a 4.5" SPOA and run 30-inch BFG ATs with no clearance problems. Perhaps the PO had larger tires on the truck before he sold it to you... if you like the 31s, removing the body lift would be a good idea.
