So I knew my 78 K5 had a rusty floor (and I'm a dumba$$), but yesterday when I went to start cutting out and replacing, I noticed that my body mounts and supports were also completely trashed! The body is basically supported by the front and rear body mounts and the doors. I have ordered the frame supports from JC Whitney but there is a long piece connecting the two that is unavailable. Please if anyone has encountered this problem or knows of a solution (besides junking the body) help me. I will post pics later to show the extent of the damage. Thank you for your time.
