Difference between auto/standard transmission injectors?

[FatManDangerous]

As the title suggests, I'm looking to get some re-fabbed injectors from rockauto for a '93 GSX... And the only difference I've found between the "automatic" injectors and the "standard" injectors is about the $5 price gap... Could anybody shed some light on this?

Of course, I'd rather pay $155 on a set of four than $175, but I'll lay down the extra Andrew Jackson if I need to.

Thanks.

Auto injectors are 390cc's, while manual's are 450cc's.
So ya if yours is a standard your gonna need the 450's.
