Huh?
Issues you will run into:
Transfer case:
We'll assume it IS a Scout 300. Bolt up replacement for a Jeep Dana 20. If you've already got a Jeep 300, don't worry about it. Buy it if it's a deal, and resell it. However, the first year for the Dana 300 was 80, so you probably don't have a 300.
Rear axle:
Stock spring perch width won't match your spring width. Weld new perches on. Go springs over axle at the same time. Net about 5-6 inches of lift with stock springs.
Front axle:
Same as above, but different solution. Mount new spring hangers outboard of your frame. Again, SOA and your golden.
Not sure what gear ratio you have or what is in those axles. But make sure the new axles have the same ratio in the front and back. (You're new hear, asking pretty rudimentary axle swap questions, so I thought I'd be safe and cover some basics - don't mean to insult if this is obvious).
