Hello. I pulled the engine out of my 66 (converting to v8 from straight 6) and saw much more frame rust than expected. The passenger side doesn’t look too bad, but the drivers side inner rail is pretty much gone from the firewall to the rad support. To replace the frame rail, what will I need to remove? I assume I will need to remove the shock and spring on that side? I cut a piece of the inner off to see what it looked like on the inside of the outer, and it doesn’t look too bad so I’m hoping the outer rail is salvageable. I already purchased the frame rail.
