I am looking to upgrade the SSD in my MBA13 early 2014.

So I'm looking to upgrade my 256gb ssd in my MBA early 2014. The new 512gb comes from the 2014 MBP the model is MZ-JPV5120/0A4. Unfortunately I cannot find any information about this model and I'm not sure if this will work in my MBP. The only other models Ive found are MZ-JPV5120/0A2 (which seems to be from MBAirs) and MZ-JPV5120/0A3 (which comes from MBA).

I don't know about those model numbers, but perhaps iFixit can help you:

https://www.ifixit.com/Store/Mac/Ma...3-Inch-Mid-2013-to-Early-2014-SSD/IF188-105-5

They list the 512 GB one as costing $600.

You might be able to get part numbers from eBay auctions for the part your looking for.
