Back to basics...A couple questions on my New A body!

Here is how option tag breaks down.

R11 END
LY9 U A31 A91 J25 N37
LY9 E2L3 000 B19 074313
E24 D13 LL29 C60 141780

Anyone help brake it down for me? Bear in mind, it is a 76, most of the decoders I have found do not go past 74?

What I have found says
A31 3.91 HP package (69-71 only)
A91 Western Sport Package (70 only)
J25 3 speed wipers
N37 ?
U denotes USA
D13 manual transmission floor shift
E24 225 1 bbl L6
