What are the Dimensions on AWANA block ?

[TAL]

I have a few of 3 or 4 different kind of blocks and have noticed differences in most...
The following are in reference to AWANA blocks:
What is the factory slot wheelbase ?
How far is the front slot from the front of the block?
How wide is the block ?
How thick is the block ?
I would think that it is 7" long, Is that correct?

I have some Awana wheels , but no blocks...
