Looks like the ole swiss cheese floor is no more. Did you use store bought patches or did you fabricate your own???...Do you have any pics of the inside of the cab???...I know when I patched mine I bought from Walcks but the rot was so bad I had to add more metal to patch panels so I could reach good metal. Did you have the same thing happen???
I fabbed all the panels out of a damaged spare hood I had laying around. I didn't grind the welds inside as well as I could have, will either coat with bedliner or carpet. Patches start at the seat riser on the passenger side and about three inches forward on the drivers side and run forward about three inches up the curve at the bottom of the firewall. Run full width also going up the tunnel curve about two-three inches to get to solid metal again. Last owner riveted down some galvanized tin and layed carpet over. Didn't realize the floors were so bad until I pulled his patches. But for a 500.00 wagon still not bad. Guy was a bondo ninja too, there wasn't any of the wagon without bondo on it, hid a lot of damage. :x . Right now only the fenderwells still need the rustout repaired. I get the metal to within 1/16" of correct or closer, that is as thick as I will run mud on a car.
