Daytona Beach,
Does anyone have the part numbers for all that is needed in a 4 bolt swap?

Mainly I need axle cup numbers. Does anyone have those?

The axles are easy - can get them at any auto part store. The diff has a B1H sticker (if I'm correct).
 
OK. I just picked one up from a junk yard out of a 1Gb Auto AWD. The sticker says J1H. Any guesses why?
 
autos have different ring and pinoin ratio... if you put that in you will fry your xfer case..( if yours is 5 speed)or blow up the rear... i no 5 speeds have 3.55 gears (around there) hope this helps... :thumb:
 
Manual trans rear diff gear ratio is ring gear 39 and pinion 11. Auto is 43 ring gear and 13 pinion. If you are buying a rear have them remove the cover and count the ring gear teeth. Or if you buy a auto rear you can swap in the manual gears but they are expensive.
 
J1h "Auto" - 2.828 3 bolt "non Locking"
B1h- "Standard" 3.545 3 bolt "non locking"
B1g- "Standard" 3.545 4 bolt "Locking"
Some one please correct me if im wrong.
