ID the threshold

[Virg464]

Hope someone can help with ID'ing what model mopar these are for. They came with the 66 coronet (2dr Hardtop) that I have, but the screw holes in the plates do line up with the mounting holes in the rocker panels. They fit in the door opening but that about it. I'm going to put them up for sale but I have no idea what they are for. Any assistance is appreciated.

Did you see if there's a left and a right?

They might be correct for a 66/67 b body. On a 66 Coronet there's a galvanized metal plate that screws into the top of the rocker panel and then the sill plates mounts to it. I'm not sure if it's needed because i think most 67's didn't come with the mounting plate.

Hi, Looking for the sill plate support for passenger side (right side) for a Coronet 2dr HT -66. Also interested in the original screws, mostly to see what type they are. Driver side (left side) in the picture. Thanks /Mattias

Those sill plate supports look familiar. I'm going to dig through the pile of stuff and see if I can find them. Thanks!

The 66”s that I have had, had sill plate reinforcements. 67 did not. Try switching side to side.
This was when Chrysler started to get cheaper building their product.
