Going SOA/shackle reversal on a CJ5 with YJ springs

Iam going to do SOA on my 71 CJ5 with some 2.5" lift YJ springs and also do shackle reversal at the same time. For the spring mounts on the frame should i buy some or build some? I know i will need brake lines drivelines spring perches maybe steering.

Where should i get the spring perches from? Also any other help you can give me.
