Unfortunately no,..good deals come to those who search, even wtb ads come with major risk, hey wanna buy my truck?, Uh ok. Any seller who can't provide additional pictures is shady or doesn't want to put in the footwork of selling a truck for thousands of dollars more than it's worth. I sold many trucks and even the most stupid picture requests should be met, ( obviously after you determined if the guy is serious or just chuckle head).
Regardless, stupid buyers not knowing what they are looking at make the truck world turn, they often pay premium and the knowledgeable buyer gets the deal when they give up. These are 50 yr old trucks, and trucks they were and used as such, they all have their issues, and 99% rust free is non existent, by 1975, these things were already rusting badly. Rant over
