We are talking about the Apple SSD's right? The 655-1837 part number is an Apple proprietary 128 GB PCIe 2.0 x2 interface for the Mid 2013 - Early 2014 11" & 13" MacBook Air's

but what's the difference between the 655-1837"C" vs 655-1837"D" also the 655-1816"B" says it fits the same computer as the 1837's so that's whats confusing me

I believe the letter is the vendor and/or the configuration of the firmware. Apple had at the start used it for the firmware rev.

I wouldn't worry about it as the P/N is the 7 digits or the newer 10 digit
