I restored a road runner convertible some time ago. I can’t remember what I did in that area.

But I would recommend stripping the area down to see what you are actually dealing with before buying anything. I think that area is leaded just like an e-body convertible.

Here is a link to my restoration pics which may come in handy at some point in your Resto.
