Full Time 4 wheel drive?

[bigtendude]

I was checking out my sticker inside glove box ( RPO's ) And apparently I have M41 - NP 203 code for this option. I only saw one gear housing, and that was in the rear. How can I tell if it really is there or removed for some reason, what should I be looking for? And what do Rally Wheels look like? These are the RPO codes in my truck....A28, DG4, F44, K30, MX1, NL2, N41, T44, V43, YCD, ZCD, ZOL?, AO1, C60, E63, F59, LS9, NA2, N33, N67, V22, XCD, YE9, ZY4, and 25D?

Forget about rally wheels. I found out that they are only beauty rings and center bowtie caps. Mine are still all there. Thanks anyways.........Larry
