OK, starting to get a better idea how this area is constructed, Makes me realize what's involved here, I know this is a problem area with this era of cabs and mine is probably at some stage of rust as yours. I will have to pull my truck out of it's narrow stall to look closer at it, I'm still debating on finding a better truck to start with or not. How was yours when you started?

P.S., thanks for the info, it's greatly appreciated.
