The 1936 wheels originally were 17" came with spokes also, but the later 16s or 15s could have been swapped. The most popular artilleries were 39 to 46 +/- and were the 15". I've found these on lots of trucks that had the same 6 lug pattern.
I found some 16" artilleries on late 30s Olds sedans, but I don't think any trucks came with 16s. As long as they are 6 lug, you should be fine.
