I’m about to dive into replacing some rusted components (69 convertible), and am not sure where to start. I need to replace the complete driver’s side rear frame rail, the complete floor pan, the driver’s side toe pan, front torque boxes, and the trunk side dropoffs. Since everything is connected to everything else, I’m not sure where to start. Remove and replace rear frame rail, then remove the old floor and front torque boxes? Remove everything at the outset and start with a clean slate? It seems like removing/replacing one thing at a time would be better in terms of keeping things stable. Advice from people who have been there, done that? Thanks in advance for any insights.
