Help ID rear ends

Went s****ping the other day in ravines got a frame and a cowl for my speedster build pre-20model t. Took a few pics of what i saw. The one looks like '20s chevy, the newer with hydraulic brakes I'm not sure of. It has a small ****** and e-brake attached as it was part of a homemade tractor. Pontiac? Also stuck a pic of odds and ends found. Headlight cans are rusty.

 

I find it amazing that you can still find stuff just discarded in ravines anymore. There is nothing in ravines around my neck of the woods except old TVs, broken gl*** and dead farm animals.

 

Getting that way here too, s****pers are s**** happy.
