VIN on a 1965 Coupe GT

['65coupegtchick]

I have a 1965 Coupe Gt and when i type in the VIN number on the internet it tells me that the DSO is Philadelphia. what does that mean? Also I think that this car once had a vinyl top because above the rain gutters and windshield posts over the doors are rusted, and where the roof meets the quarter pannels are rusted out but shows to have body filler. I Cannot locate the trim tag so I think that it has been lost over the years. The VIN number is 5F07A352059
Date- L
Body- 65A
DSO-23
Axle-1
Transmission-5
Color-M
Trim-25
Engine-A


I know all the facts that the decoder has given me so if thats what your going to give me then its no use. But if you can possibly find the trim tag number out of the VIN number please do so or show me how to do it. You can email me at general_lee69dc@yahoo.com or IM me at yahoo at general_lee69dc
Thankyou,
