the part number for the mufflers is 11236 i dont have a video or sound clip for them but they are like brand new and you shouldnt have to weld them because i just have clamps on them now and it holds fine. its 2.5 inlets so it goes into the catback. dimensions are 4x9 for the muffler and the length from the inlets is 20 inches. It says they are a universal fit and most mustangs almost havethe same exhaust design so id imagine they would fit. i have them on my 95 gt i cand send pics if you want. i dont know how to upload a sound clip or anything if u know how tell me so i can do it
