sorry to hear about your car and i hope you can get it fixed, im sure you already have but i would ask the person you bought the car from for recipts to the aftermarket parts put in the car which will have dates the items were purchased and maybe you can get conpensated for the loss of the parts, but in all honesty optima if the do pay and there insurance company will probably only give you blue book value for a 88 mustang gt. it sucks but its true youll probably be better off buying a doner car to put your reusable parts in and start from there. hate to be a downer but i had to throw that out there. good luck
