also where are you getting yours sills from. i cant find any.
Good Answer Rusty
Im a distributor for Hadrian Body Panels and most of the sills i have sold have small lips recessed out on the lip edge where its spot welded to the inner sill and if they are not present then i usually drill into the inner rear arch 10-12mm and inject dinatrol from there. Then use a rubber grommet to close off and underseal.
No wonder all the minors are rot boxes
Drain holes are needed to allow water to escape, .
