Found the next piece...
 

Picked up a 292, out of a 1966 but definitely a much later motor. Complete. Was fun to watch the clutch fan spin on the way home.
Now have 3/4 4wd chassis, motor, cab that needs only rockers and corners, rust free clip.... Just need trans and bed although flat bed looks interesting.

And motivation and not raining.

Nice. The 292s seem really hard to find. Wish they still did a crate version of the in-line 6
