Walt,
That is a Chevy Hood from a '62 to '66. Also if the door you got was from the '64 1/2 ton you had mentioned in the other post, it will not fit. Only doors from '60 to '63 will work on your truck.
Check the engine numbers on the pad on the front of the engine and it will tell you what size V-6 you have.
Also sometimes when a car or truck is running down the road fine and you hit a bump and it won't stop shimmying, it can also be the pitman arm.
Keep us posted.
