Thanks for the comments guys!
So we had fabricated a duplicate of the 55 AC car battery tray to get the battery off the firewall. This bolts directly to the outside of the core supports "horseshoe".
So when we decided to widen the opening for a crossflow, the tubing had to be placed directly next to the old upright to locate our battery support in the same location.
This means the new uprights would also conflict with radiator necks. Dominoes, they do fall.... Core support now with relief holes for coolant hoses and lines. Thankfully side baffle plates will hide this ugliness!
