If all 70's truck started rusting almost immediately there wouldn't be any around now without some intervention within a few years of new. They'd have completely rusted away by now. But there are some that are original body and even paint that have not withered away with rust such as my '79 from California. Yes cars and trucks from that era and of most makes were prone to rust but luckily many are "survivors".
Mine was considered a " survivor" . There just isn't much point into pumping 15-20k into the outside resto when you know rust is lurking within. This truck could have been prettied up and been nice 9/10 for another 5-8 years before the rust made itself known in the structure again. I'm in for another 8k over the origianl resto guestimate, but I will not only have a truly rust free truck but also a rust resistant truck. It's treated, sealed and rhino lined inside and out, as I intend to use it year round. It will now outlast me.
