Congrats on the new forum, and hanging on to the 1.5 ton.
What's the height? According to the 1952 spec book:
for the standard 4403 cab & chassis, without body & payload...
from the ground to the top of the frame rail is 32.75 inches...
top of frame rail to top of cab is 52.5 inches.
Add the two and you should be pretty close
to what the 1949 height is.
