replacement rocker panel differences

[hemiorange]

I am looking at some rocker panels from classic2current and they list two different ones for my 70 dart swinger. I am having a hard time differentiating between the two.

This is the only info on the listings:

1967-76 Dart 2dr Outer Rocker Panel, RH
[190-010-2]
Fits 1967, 1968, 1969, 1970, 1971, 1972, 1973, 1974, 1975, 1976

1967-76 Dart 2dr Outer Rocker Panel Ext
[245-010]
Fits 1967, 1968, 1969, 1970, 1971, 1972, 1973, 1974

Does ext stand for extended... meaning it's longer? I tried emailing the company but got no response.

There are a lot of different names for inner structure... the rocker ext... is probably and extension panel inside the rocker, on the back or some place else that ties it into the car. I have never done one on a dart or abody so I can't exactly tell you where it would be.

I got a response back from the company and they said that the ext version means extended and they would include a portion going into the bottom quarter panel. exactly what I am looking for since the last ones i ordered came up about an inch and a half too short.
