The HID Headlights are standard on the SRT.
Im not 100% sure about the Electronics Convenience group, but I think it comes with the My Gig package.
As for the tranny and Trak Pak, it costs $695 on the SRT and $995 on the R/T.

(edit) I was looking over the documentation Ive accumulated from here and at other sites. The Electronics Convenience group is standard on the SRT.
