Rear axel from 1981 G30 van

[grey83c20]

Found a Craigslist deal on a 14 bolt SF rear axel out of a 1981 g30 van that has been in a warehouse for 20 years supposedly. Wondering if it would fit my 1983 c20. I have the exact axel in my truck but I've got a bad pinion bearing that is howling very loudly. At $850 for the repair of it I'd love to just get a used axel.

Thanks!

It won't simply bolt in. The spring perches and shock mounts would need cut off and welded on in the correct location for a truck. Track width is a few inches wider too.

That's what I needed to know. Thank you

Found another axel that is a ff 14 bolt out of 90's dually truck. Would that be a bolt in situation for me? Or are axel tubes longer for a dually?

Same scenario as my other post. Basically the only thing that bolts in is an axle from a C20 or K20, and the K20 would probably have shorter shock mounts.
