I ran the decoder WOW cool program but I have a couple questions what is the differance between the RPO G80 & G92 and does any one now what the RPO 1AY is this is on my list I have checked it twice but the decoder gives me ????? has any one seen this before.

 

1AY - Vehicle was custom built per dealer stock order
G80 - Posi differential
G92 - Axle performance ratio (probably either a low gear ratio or 28 spline axles.)
