Not quite seeing it, any ideas?

I am working on making a model of the part shown below.  I beleive I have .375" cut correct shown in 2B2-4 but I can not for the life of me see how to do the other cut shown in 1B2-4.  Anyone see how this is made.  I have attached the model of what I have so far. 

Thanks,

Chris
