i will prob do it this way,but even if i slice at the rail i still cant get the old piece of 1/4 out from under the roof?and i just looked my amd s dont have the lip that folds under the rail like the origonal?


You will leave the old piece under the drip rail, then trim the new quarter to fit that area, then mig weld the new and old together at that seam.
This means you will leave the drip rail alone completly. Use a cutoff wheel to slice the "C" pillar along the edge of the drip rail to separate the quarter from that area.
