How does the right inner wheel well connect to the fire wall? On the left I have a curved "Z" assembly that combos to connect the left wheel well and reinforce the parking brake. I'm assuming the right side isn't much different, however I have no pc that resembles that. If my assumption is correct, how did this pc connect to the fire wall? bolt or weld? Has anyone seen this illustrated in the '47-'50's assembly manual? section n page?
