Super work on that body. Something I would like to mention is, you should install regular ball joints in place of the heims. Coming from a lot of off-road fab and wheeling experience, We use heims for off road use only! Anything streetable should run standard ball joints.
In my build currently I am looking a failure in my split rear bones as well. Might want to read the mentioned link on Jalopy Journal. I need to rethink my project now!
Keep the pictures coming!
Thanks for sharing.
