Can some tell what TC this is and also how can you tell if there is a sye installed. Thanks.

 

There's no plate under all that dirt on the back of the unit? (should be a round metal tag)There doesn't appear top be a SYE from the super long tail case. That's where the slip yoke usually is, from what i can see i would guess a NP231, but that's just a guess

 

I was hoping there was a sye....the shaft seems longer than the one on my 98 and a bit bigger
