I Concur with all of the above BUT,
After Rereading the opening post,I have Questions.
You say its a 49 3600,
Then why are the pics of a 3100?
Could it be that a prior owner cut down a 3/4 ton truck to a 1/2 ton wheelbase?
Are the wheels/hubs 6 lug or 8 lug?
Is the door plate/serial# tag still intact and what does it say?
Could very well be a "put Together truck" especially seeing the doors are 1951,with the pulldown handles AND Ventwindows,the only year available.
Dont Misunderstand me as Knocking this truck,as it is Beautiful,Just trying to show some facts
