1968 Formula s 340 Here we go again

Bad News guys, Front sub frame is rotted beyond my capabilities.
I will continuation to make it run & drive since i need to make it drivable.
Or buy a Roller to transfer Engine trans rear.
I already ordered the parts i need to do so. Drums, brake lines Etc. she runs now just have to get brake lines on.
Unless i can find someone who can or wants to save this #’s matching 1 of 1074 made 340 4 speed Formula s. Cars.
Here is a pic 2nd pic is looking down from top.
So far investment is $7250.
not buying a carpet that was my plan “$500” and New Tires $300+.
That being said i know anything can be fixed with the right talent and cash.
Just not feasible for me.

I would try to get any loose crud out of frame rails maybe go up with coat hanger try to get loose debri out. Also crud hangs up in the tops of rails by A Arms. If you get debri out of rails and off the top of rails then it wont trap moisture and would slow down the rusting.
