Technical 1946 Ford Pickup cab mounts

I'm putting the cab back on my '46 truck frame with new wooden mounts. It's obvious where the four largest pieces go but I can't remember where the two small blocks go. Can anybody help please?

 

Long blocks are at the front of the cab and the larger blocks are at the rear of the cab. The two small blocks were not used in the two different pickups that I've dealt with. They would fit up towards the center of the cab. Not sure which application they were used in...possibly on the big trucks or panels.

 

Thank you Double Pumper. Puts my mind to rest.

 

Where did you find your wood kit? Or did you make it?
Thanks,
