The only way you are gonna find out what options it had installed,is the build sheet,also known as the TANK STICKER,it's on top of the gas tank,you might be lucky enough to have one,probably not.the window sticker will have it too,.the best way to get to the Tank Sticker ,is to drop the fuel tank,which can be a P.I.T.A.,unless you are tearing the rear end out anyway.Go up too the tools bar on the home page,and point on tools,then C3 statistics,and you can see all the options and codes,that were available on 78s,and pick out the ones that are on your car,that will give you a vague idea ,what you've got
