If you paint it OD and put the National Emblem on it (as 99.9999% of the European returns are) then you should put it back to GI service. I consider it lazy, and a sign of disrespect to put the Army colors and markings on a truck that is still 99% European configuration.
My truck will be as perfect as I can make it. Anyone can buy a truck, paint it green and say its a WWII CCKW when it fact it never saw US service in that configuration. If it was as easy as picking up a JC Witney catalog then everyone would be doing it... but since anyone can buy a truck and paint it OD and put stars on it they need to be educated on what IS a CCKW as what is not. Most trucks out there are NOT...
Enjoy your new truck... you list quite a few MVs in your sig so you should know that bolting on the part is the last, and easiest part of the process... you have to find it, then make sure its the right model, then rebuild it, then you get to bolt it on.... and its a great feeling when you do.
