When I took of my front fenders there was no spot weld (87 as well). You will need a raiser blade and score along the top and side of the inner fender. You need to separate the undercoating between the fender and inner body. In the pic below score along the red lines.
Let me know if you want me to email you the full size image.
However, rattle snake has much more experience than I do and I can only say what I did for my car.
