hi, i just recently got the time to type in and find out what all of my rpo codes mean. below i have listed the ones that i dont understand what they mean. if you could, can you explain what they mean?

E72- Body Lenght incr 18 inch
E52-Door RR, 83 inch wrap around
C60- HVAC system, air conditionior FRT Man Controls
1AY- Stock orders processing option (dealer Ordered Car).....this puzzles me the most. does this mean the origional owner got it specially ordered and had it shipped, or it was on the showroom floor and was purchased the day he walked into the dealer?
8NL Computer Selected Rear Lefthand Spring
9NL- Spring Computer Selected Rear, Right hand

These arent all the codes,just the ones i didnt understand the meaning of. All of the descriptions were form this sites "RPO DECODER"

thanks albert III

 

The dealer ordered RPO code is just that, a car that was ordered by the dealership for their inventory, as opposed to a customer ordering a specific car which is RPO 1AZ.

E72 is wrong, the eighteen inch body increase is probably for vans. E72 means something different for f-bodies don't know what though.

E53 is the same probably for a van not an F-body.

The springs are self explainitory, a computer selects the proper springs for the car based on the options the car has.

 

the only code i didnt get was YA7. says unable to find in database. anyone know what it what might be?
