Is there a secret decoder ring for Lycoming engine variant numbers?

[Kiddo's Driver]

The only difference I can figure out between an IO360-C1D6
and an
IO360-A1B6
is that the C1D6 has a rear mounted injector.
Is there a secret decoder ring for this?

Not the TCDS, but gives the TC numbers for each variant:

Got it, thanks!

Edit: removed useless link and attached PDF.

The TCDS was what I really needed. It lists the exact locations of components and connections so that I can see the difference.
