Bill,
I used angle ally along the sill panel with the same wx-stripping I used along the spider. I think it was 3/4" which I had to grind down the verical side (slightly) to fit under the door.
I made a piece to go straight from the spider leg toward the front and the a second piece which attached to the dash pillar (was bent 90° at the bottom toward the sill panel) and bolted together at the front end of the first. Some of the details are mildly visible in
THIS POST.
The long piece will be epoxied to the sill panel and the wx-stripping is one continuous loop starting at the base of the windshield. We'll see how well it works if it ever rains in PHX.
