Are they 5 on 5.5?  Same bolt pattern?
If somebody can find the 'magic donor' vehicle it would really help us all.
I've searched high and low for the perfect fit.  And have even gone as far as making my own Hybrid Suzuki front end.
We've found that the FJ80 LC axles have the correct offset and have lots of kewl features available to them.  Sure, they are a bit wider, but not outrageously so.  Especially if you guys are already runing greater than stock off-set rims, ~3.75.  The LC axles with normal offset rims, just might be your answer.
(it's not too wide.)
The major downside of FC80, LC axles might be considered the cost.  But if you add up the costs to make any other axle equipped with selectable lockers, full floater rear axles, high pinions, and front AND rear disc brakes, it really ends up being a wash in the end.
Please, if anybod's got anything closer let us know!

I was just mentioning it as a possibility due to the offset axles. To add, prices for their axles, complete with arms, brakes, and steering, is roughly under ~$300 in the midwest!! The wheel lugs are 5, but don't know the configuration. The axles are encased (closed knuckle), have splined drive flanges, available gearing up to 4.8, air or cable lockers available, drop out centers, 4-wheel discs with matching rear, and in some models, rear full floater and drive flange pinions. Similar to that of the Toy FJ80's, but with much less upfront cost, hehe. Note: most stock axles won't have the deep gears or lockers. Just special models will have this. Lastly to add, the drag link for the front axle is high mounted on the knuckle (above it acutally) and the tie rod is behind the axle. The control arms are similar design to that of the FJ80s with the front of axle and rear of axle mounts. Mounting these to the Suzuki frame would be rather easy with a simple mount or crossmember. About the only problem would be the coil spring mount (not knowing the coil mount width on the axle or frame width).
Mind you, Land Rover is not as popular as Toyota for parts, and will probably pay a great $$$ at dealerships for small item parts, the late model Discovery model weighs nearly 5800#s, I figure the axles could endure underneath a Suzuki. Though do look at all the US aftermarket sources for the Land Rover Defender90, Discovery, and 110.
PS. I missed out getting the front axle for $250 from a Discovery almost locally. The arms, coils, steering, brakes, everything complete. Matching rear would be added for a mire $200. DS extra but probably cheap.
