* Front: A Dana 44 high pinion. This was very common, especially for 4x4 models.
* Rear: This is where there's more variability. Common options included:
* GM 10-bolt: A common, lighter-duty axle.
* GM 12-bolt: A stronger, heavier-duty option.
To know for certain what axles are in *your* specific 1983 Chevy K10, you'll need to:
1. Check the vehicle's documentation: The original paperwork might list the axle specifications.
2. Look at the axles themselves: The axle housing usually has casting numbers that can be used to identify the specific axle. These numbers can be looked up online in databases or parts catalogs.
3. Check the differential tag: The differential cover usually has a tag with identifying information.
Without more specific information about your truck (trim level, options, etc.), it's impossible to say definitively which axles it has.
