what vintage trucks are these?

[t-maxxracer32]

so today i was lookin through some old stuff and refound these older trucks. i may do what hummerman and try restoring a couple of them for the fun of it.

i would really like to know what that chain driven truck is because it would be the best candidate right now. (all it needs is body and 1 dogbone.)

thanks for any help you guys can give me on these trucks!
