73-76 a-body k-member

I have a 73-76 V8 k-member but I am in Mississippi shipping might kill you. 125 plus shipping. I also have lower control arms with tabs for the same k member
If I get it, can you check the shipping to 92585. In my experience, fedex is cheaper when it is over 15 pounds. Also is there anything special you need to do to make that k-member work with a big block, or is it better to get a biscuit style K-member to fit the big block?
