as the name says, what is option package 03? the rpo code is 1SC. Also i couldnt find what out what the rpo code 1SZ is. I own a 1992 camaro rs with 700r4 and 305 tbi.

Thanks in advance

 

The "1S packages" were/are a RPO code GM uses for a combination of options grouped to ease ordering and building,and in most cases give a discount over the individual cost of the options.They came in different levels;ie 1SA,1SB etc.It did take away the fun and ability to order your car how you wanted it.

 

Here's the 91 option group packages.

 

hey thx for the replies, so i guess they just put the options in packages
