Need some specific SM shoulderpads

Looking for some of these SM shoulderpads. I usually just order a bunch from bits stores, but I'm going to enter my Space Sharks rhino/razorback in a Badab war themed competition at Bell of Lost Souls, and I need a couple of these quickly to complete the turret/hatch guys.

Here's a pic
