(I'm sure Darrell will have some useful diagrams 
)Pretty much all external components on SJ axles are interchangable i.e. Stub axles, hubs, swivels, seals, bearings, freewheeling hubs. Internal components differ between the 410/413 and Samurai axles i.e. diffs, axle shafts and CV's are not always interchangable.
Ratios & diff interchangability
410= 4.11:1 (37crown wheel > 9pinion)
LJ 80= 4.56:1
Front are 22spline and rears are 26spline.
410 and lj80 diffs are direct swaps although on late SJ410's the bolt spacing on the diff flanges for the props is different
LJ80s and skinny prop SJ410s (upto 84) are 50mmx50mm with 8mm bolts
Later fat prop (85 onwards) SJ410s are 56x56mm with 8mm bolts
413= 3.909:1 (43 crown wheel > 11pinion)
Samurai= 3.727:1 (41 crownwheel > 11 pinion)
Front are 22spline and rears are 26spline.
413 and Samurai diffs are direct swaps Although some Samurai's built from 1990 onwards have a larger bolt spacing on the diff flanges.
up to 89 56x56mm with 8mm bolts
Later models from around 94 onwards are 60x60mm with 10mm bolts
SJ410 & lj80 diffs are smaller than SJ413& Samurai diffs so you cannot swap them.
You can fit Vitara and early GV FRONT ring and pinions into 413 and samurai diffs, the available ratios are as follows.
Vitara
swb manual=5.125:1 unless it's a later model 4u/4u2 etc then they have 4.875:1
auto=4.6:1 or 4.3:1 depending on transmission.
commercial & lwb= 4.88:1
Grand Vitara (to the best of my knowledge)
98-05 G16 manual and Auto= 5.125:1
98-05 J20a manual= 4.875:1 auto= 4.875:1 or 5.125:1
98-05 H25a manual= 4.3:1 auto= 4.875:1
01-03 XL7 H27a manual= 4.3:1 auto= 5.125
03-05 XL7 H27a manual= 4.3:1 auto= 4.3:1
98-00 RF 2.0 diesel manual= 4.3:1 auto= 4.3:1
00-03 RHZ 2.0 diesel manual= 3.909:1 auto= 4.3:1
04-05 RHW 2.0 diesel manual= 3.909:1 auto= 4.3:1
Front 22spline Vitara diffs are a direct bolt into Samurai/413 axles but if it is an alloy diff it is best to swap the ring and pinion into a steel Samurai/413 diff. Rear diffs are larger and do not fit Samurai/413 axles.
Axle widths
(all dimensions are wheel mounting surface to wheel mounting surface)
Samurai front= 1333.5mm (52.5") rear=1326mm (52.2")
410/413 front= 1232mm (48.5") rear=1224mm (48.2")
Jimny front= 1355 mm Rear= 1365 mm
Spring perch spacing width
(spring locating hole centre to centre)
Samurai front=720mm(28.34") rear= 950mm(37.4")
410/413 front=640mm(25.2") rear=870mm(34.25")
To fit samurai axles onto a 410/413
Each front & rear perch needs to be moved 40mm inwards.

Seal should come in the bearing kit fram any motor factor
if desperate could try a 50x68x7mm oil seal but it doesnt have the extra lip to keep the crap out.
