Option group A53, 1979 911SC?
 

I have a 1979 911SC. I have the original window sticker, and it lists a lot of options; leather, air con, silver met, speed contol etc. It also list option group A53. I have found in an older tread that option group J17 for a 1981 911SC was;

Pirelli tires
Radio
El. mirror pass side
Forged 16" fuchs
El. antenna
Sport shocks
amp
white fogs

My car has in addition to the options listed on the window sticker;
Bilstein shocks
Fogs
El antenna
radio
etc

But I wonder what the exact spec is for the A53 option group is, it probably include some of the above options not listed on the window sticker. The A53 group was priced at 2535$, and the total price at 29584$. Base price at 24325$.

Thanks
