Went down to the garage and snuck in about an hour of work on it........
I tacked the upper shock brackets and set the axles to measure for the housing getting wacked. My initial measurements so far were off. It is going to need 2.5" on each side shortened. I will check it again tomorrow when the wheels get here.
When I pull it back apart to finish weld it all, I will be adding gussets in a few places across the brackets, along the frame connections for the shock tower etc. Then it will go to be shortened.
