4 door rockers compared to 2 door rockers

[mopar4don]

What I have here are 4 door rockers from a 69 Coronet that I was hoping to use on my 69 Charger restoration.
I have them next to each other for comparison.
The first thing you notice is the 4 door rocker seems to be a bit longer, like it has an extra tail?
Should this be there? I'm thinking not.



Another view of the extra tail.


My main concern is the area of the charger rocker (where I am pointing) behind the door jam, under the rear window.



You can kinda see where the rocker changes levels, it bevels down. On the 4 door rocker it does not do this. It runs continuously from front to back.
This area would be under the quarter panel and I was wondering if it is clearance for the quarter panel?



I'm not sure these 4 door rockers will even work?
Please I need some advice!

I don't remember the extra tail. I'll have to go out in the yard and see what I have.
As far as the bevel under the quarter skin the 4-door rocker would not have that. Not sure of how you can make that work.

Yes the bevel is to flush out the rocker with the quarter

Will these 4 door rockers work for the Charger?

I don't know how you'll make the indention for the quarter panel to flush out. I usually only save the front section of 4-dr rockers.
Kinda hard to see but starting just below the jam back is lower. I'd think a good metal man could recess this area but might be easier to find a 2-dr rocker. This is a 71/4 but no tail.

I'm open to some good used 2 door rockers... anyone have some they want to sell?

Moparmarks is right, no tail at the end of the 2 door model. '66-70 (similar to 71-74 rocker above), It actually elbows in 90* at the, and the outer wheelhouse spot welds to it from the inside. You could create that transition yourself with a little handy fab work. Look doesn't have to be pretty, just got to get the fit right. Cut the panel width wise where the transition begins. Next would be to add a piece of metal off the forward cut end and match it to the slight angle of the factory transition. Length wise, the transition area is pretty short, like 1/2". Important part is to get the angle right so it recesses and fits behind the quarter, but not sitting too far back. Next you would need to graft out a strip of metal in the top and the bottom of the rear piece of the panel so the upper and bottom lip/edge are lined up parallel with the front. Also, fill in the gap on the top and bottom where the transition is. Last would be to cut the rear of panel to the proper length to mate at the wheelhouse and weld on the 90* ears that fold in (like in moparmarks picture) to mate up. One thing that should be mentioned is there is two areas of the rocker (that is underneath the quarter, on the bottom) that recess down and spotweld to the bottom of the quarter. You'd probably want to fab up something for those as well. I don't now about the 4 door rocker, but with the 2 door there is also a couple internal braces (begind the quarter section) that weld from the top lip of the rocker and then take a triangle shape to spot weld to the bottom side of the rocker.

Looking at it, I would imagine a guy with moderate/decent fab/welding skills could probably have that all done on both in a full day. Sort of time consuming, but you may end up saving yourself a decent amount of cash. Unfortunately finding decent used rockers is pretty tough, being they're one of the first things along with the wheelhouse area that love to rot out first. You're from the rustbelt, so you know what I mean.


Good luck
