Sanded the top cover windscreen joggle. Repaired with Bondo small imperfections. Sanded again. Trimming of the Windscreen to 3/16" gap to the cabin top. Used temporary wooden shims to simulate final position. Clamped the windscreen to the cabin top cover. Marked with the 3/16" marker. Disassembled and sanded with 150 grit doing radiuses on both edges. sanded with 250 grit. repositioned and it looks good.
next step will be to sand the flange, position the shims with rapid epoxy and reposition the windscreen cutting the shims to measure. Possible need to further sand the windscreen top.
