i just got on here i have this problem i bought a 87 mustang lx 5.0 auto. and its 5 lug and i need a new rear end for it and i want everything to bolt up like the one does up under it now. i took the code tag off the pumkin and it reads 2SL73A887B05 or 2SL73A887805 its hard to make out. but ive tried both and cant seem to find a match any where. any ideas? the top number is 201A.
