Check out these two places:
www.roversdownsouth.com
www.tntlr.com
I've done a lot of business with tntlr and they are quick. However rovers down south is a lot cheaper and TONS cheaper than rovers down south. Watch out though, the guys at rovers down south...they can act a little strange sometimes so don't freak out and run away. Go along with the shenanigans, laugh, then get your parts.
Ditto on Larry at Rover Auto. They've got plenty of used parts laying around.
The rovertym suspension is pretty good stuff. Main thing is to get their front diff cover. It is a weld on unit but a good one. The clap-on style diff covers are ungodly worthless. One hit and they fall off the truck. Not to mention the crappier version costs more.
A 2" lift will allow you to easily fit 31s so a 3~4" will allow plenty of room for 33" tires. The stock rims are 16". If you don't want to keep running 16" rims (which I can understand) then check out
www.gulfcoastrovers.com.
If the truck is gonna get wheeled, keep an eye out for spare front axle shafts. They can be had used for a reasonable price and having them on hand is nice.
The rear will readily accept a detroit locker. Call up Performance off road center in ATL. Last I checked they had the best price said lockers. At the same time, upgrade the rear axle shafts.
www.rovertracks.com offer aftermarket shafts that are pretty cheap. The reason I say that is if you do break a rear axle shaft, it'll kill the locker.
The front axle is a little tricky, either a LSD or air locker because of permenant 4WD.
I'd recommend getting custom rock sliders made (if you can do it, good for you, if not a shop). All the bolt-on rock slider kits out there bolt onto the body. Well the body is made out of aluminum and when the slider takes a hit, it bends the body. Tieing the rock sliders into the frame is crucial. Also having the rock sliders protrude out helps protect the body.
Replace the steering hose lines. These have a nasty habit of springing a leak and causing the truck to catch fire. This is a pain in the rear.
The rover comes stock with cross over steering. However look heavily into a steering stabilizer relocation kit and heavier duty steering links.
The 94~95 models have a nasty habit of puking their cyl. head gaskets. However if you've ever worked on a pushrod V8, thats all this is. Be prepared for this.
The rear driveshaft is connected to the pinion via a rubber thingie called a rotoflex. If it looks old and worn, replace it. Better yet look into a u-joint conversion kit (uses components from an older Range Rover). However simply replacing the rotoflex is usually good enough. On that note, I would recommend getting both driveshafts rebuilt. There is a shop, Carolina Driveline that can take care of you (google that name). Ship them the shafts and they will handle it. The price is right as well. Balancing both shafts is just insurance against blowing up your t-case or pinion bearing.
Check condition of engine fan clutch. Do this by grabbing the fan and then wigglin' it. If it is solid, then its fine. If not then replace.
The engines are weak in these trucks but fairly durable. The transmissions are solid as are the transfer cases. The axles are pretty retarded. Full floating rear with full floating kingpin in the front but still kinda weak. Stick to the ~33" and it'll be fine.
For lighter wheelin' the rovers are pretty awesome. Comfortable but still fairly capable. 3 link rear and radius arms in the front, all the links have decent length to them.
Check front track bar bushings. They have a tendency to go bad and give teh death wobbles. This is sad.
Check all wheel bearings. They are full floating so treat accordingly. However grab the tire at the 12 and 6 o'clock positions and then wiggle. If the tire moves, wheel bearings need to be replaced. You will need to purchase a special tool to remove the lock nuts. Call one of the rover shops above for said tool.
If you avoid the dealer and buying parts from places like Atlantic British or Rovers North then the price isn't gonna be any worse than a jeep.
There is a little metal clip in the transmission shifter knob that sometimes brakes, causing the transmission to lock into park. To fix this, take a small slotted screwdriver and pry off the top cover. Then grab the silver rod in the middle shifter and pull up (with the brake depressed). You can then shift normally. I tell you this trick because it'll freak you out when your stuck 20 miles back in some trails and the damn thing won't shift. Also the brake light fuse, if burnt, will yield similar symptoms.
If it doesn't have trailer wiring and you want trailer wiring...its a pain in the ass. Plan half a day and a case of beer. Thats all I have to say about that.
I bet that truck hasn't been shifted into 4 wheel low or center diff locked. Tell your buddy to start workin' it to free up the linkage. They get stiff/seized due to lack of use. You can crawl up under there and play with it.
On either side of the transmission on the firewall in the engine compartment are two little "nipple" looking things. These are the drainage pipes for the A/C condenser. The "nipples" get clogged up and then water spills out on the carpet inside. This is annoying. Take a screwdriver and pop them out (this is what the dealership does). The nipple things might have already been removed, but if not, handle it.
Under the passenger seat of 94 and 95 models, there is a little red/brown looking box. At certain intervals this box throws the "check engine" light (or one of the lights), forcing you to bring it into the dealership. To fix this, remove said box from truck (pick your choice of disposal). This box might have already been removed so if you don't see it, be happy. I think the box says, "Emission maintenace reminder" or something. Its behind the glove box on 96' discoveries.
If the window randomly falls down, its the track assembly. Instead of replacing, find a friend with a welder. There is a spot weld that commonly fails and isn't "fixed" on replacement units. Having it welded will be cheaper, easier and a better fix.
Figure out how to replace the cabin filter. Its probably never been replaced and will make the climate control work so much better. I recommend this for any used vehicle.
Overall these are pretty reliable trucks. Its always little shit that breaks. However driving in Uwharrie with the windows up, A/C on recirculate is DA BOMB then asking random people if they have cheap mustard in a jar.
Enjoy.
