well I had done more digging into this rust BS and of course found more/got worse. The pass. front pan has swiss cheese holes around the size ofa pencil eraser all over, pits that are bad, and all seems to be from the topside.
The pan the put in back on the PS, well it's not spot welded to the floor support brace, in fact the front is like 1/2-3/4 inch off it and in back it's 1/4-1/2 inch off it. So I think a full pan from toeboard to rear seat is in order, removed their crap and install full pan. Or I can do a front piece and a rear as the section inbetween over the front brace is fine.
The DS is not bad, I found one tip pin hole in the rear around the size of a pen end, like 1/16 of an inch or so, barely noticeable. The front where the firewall brace runs behind the toeboard, the actual toeboard has some holes, not bad and not thru as the firewall piece is behind it.
Now the NEW BAD, pass. rear frame torque box area has some kinda bad rust, scale pits, some swelling and bursting out of metal on bottom. I saw no holes just that spil from where rust got in between the layers and caused it to swell and split or seperate. I also noticed that entire rail going to the back had some bad rust scale on it. Not sure what I'll do, thinking wire brush by hand or drill and por-15.
I am also strongly thinking of aking a "tip over" jig from wood for it, as some have done on youtube or fb for their 2nd gen f bodys, Since poor boys got poor ways, I got no concrete floor except out in the carport, and no money for no $800 dollar store bought rotissere, nor can I build my own with steel because of my lack of welding.... LOL I think this wood deal may be my only really good option to really get in there, clean it, fix it treat it etc. Plus it'd be easier then trying to lay under it, or jack one end or one side high enough to do anything. It will let it lay vertical like 90 degrees on the side, like a store bought deal, but only that position, which is perfect for me. I'll have to do some more research on materials and some looking at mine and go from there. I wanted to do the same on the camaro, but then wanted a 4wd squarebody bad, and then couldn't have 2 projects, one being neglected etc. Then sold it to Andy, then found the bad crap on the square, and just stumbled into the TA, now back to the same old BS as before. I think I'm being punished for not just fixing the camaro. I can't seem to get away from frame issues.
