It's hard to tell the 3200 from the 3600 as the sheet metal and frames are the same.
Your 3200 serial number starts as V3B59.
If it's a 3600 it will be V3E59.
The 3200 has either 7 or 8 rear leaf springs, while the 3600 has 9 or 10. Other than the axles that's about the only difference.
I'm not aware of any RPO putting 3/4 ton axles under a 1/2 ton truck, why would they do that???
So, you either have swapped axles or a missed stamped series in your serial number (B should have been an E) from the factory...
