The information below is about the 1940 models, but I think that most of
it will apply to the '46 models.

That sounds right. The Forty came without a heater - The one that has
been in ever since I can remember has a big MW emblem (Montgomery Wards)
on the front of it. One of the hoses is connected to the water pump and
the other goes to the housing where the upper radiator hose connects.
It never worked very well, probably because the engine always ran cool.

The 1940 Chevrolet Truck Data Manual for Chevrolet Salesmen has
specifications for shocks up through 3/4 ton. There is no mention of
shocks on the heavy trucks. Looks like they didn't have any.

I remember when my Dad installed signals on our '39 Chevy ton and a
half, probably about 1960. The kit came complete with all lights and
required no modification of the truck's wiring. (They were available
with self
cancelling OR 4-way flashers, but not both. Dad chose the
self-cancelling kit.)
Dual filament bulbs are available in 6V. Last time I looked they were
also available in amber as well as clear. That's what I used when I
modified the front parking lights to put turn signals on The Forty, back
about 1974.

That's way more complicated that necessary.
