Larry,
I can't help with patterns for the interior trim. Hopefully someone has them and will help.
You stated: The '32 panel
. Actually it uses the same headlight as the 1931 trucks. Looks like the '31 passenger but bucket is steel and painted black. Rim is chrome plated.
And:
the spark,choke and throttle cables are like the 1930, 31 cars they are not grouped together as a 1932 would be in the center of the cowl
The cables are positioned exactly the same as 1931 models with the addition of the minifold heat cable in the center of the dash above and between the speedometer and Water/amp gage.
They are minor points but I am sure you want it right so mentioned them.
