Don't know the difference, but my upper screw was a biatch. There is a frame piece that blocks direct access to the screw on mine. I used a Craftsman #1 philips regular screwdriver. The standard philips is a #2 and it was too large to get a bite on the screw. I was able to pop the original light out of the bracker so I could see exactly what I was dealing with. I had to put it back together blind which was harder than removing it.
Ultimately, I guess someone with a pre-98 can give you a better grip on this. My 99 SE Sport was different than the SVT picture, so there probably is a difference among brackets.
