i have option #3 on my 87 IROC-Z. yep im bored. and there was only #1,#2,#3 option code levels correct?

 

Sort of. Depending on the year there were up to 4 option levels.

 

what was included in level 4? 1le?

 

My 1LE was
option code 01 1SA
Aero package #4 WW4

But keep in mind 1SD didn't exist every year. Take 1987 for example, 1SC was the hotdog package. Typically 1LE's were strippers, hence 1SA.

 

I'm driving a 20 year old stripper!

 

thanks i looked at the thread earlier and thats where i got 1le in option #4 from. is there a thread telling about what all the rpo codes mean?

 

Probably not, since it changes by year and almost universally no one on these forums is very well versed in more then a couple years. For example in that thread it was do-able cause we knew the subject and had the resources available. Probably the closest to a complete resource would be the Camaro White Book, but for what's a $12.95 book, I doubt it's worth anyones time to type it all out.

To add additional confusion, the option packages meant different things on different models.

 

I should clarify... 1SD existed in 87, but not on the Irocz

 

ok thanks anyway so what is 1sc?

 

i can't comment on that with out getting myself in trouble
