GEN 2 Gen2 rear axle housing part#?

[BlackF-R50]

Can anybody confirm the correct part number for a gen2 rear axle housing? I've called two different dealerships and they gave me two different numbers. BL3Z-4010-A / HL3Z-4010-E / HL3Z-4010-A , can anybody confirm which is the correct part#? Thanks

It's HL3Z-4010-A on tasca, BL3Z-4010-A from one dealer, and HL3Z-4010-E from two other dealerships
