49-51 Merc INNER rockers

I've got a 51 four door Merc that needs inner and outer rockers. I figured I can build my own inners. Was wondering if anyone had any measurements or pics of how they terminate toward the rear of the car. I've got about 10in of the front of the inner rockers to work with..... just need to know how and where they terminate in the rear of the car. Thanks

 

I have the dimensions for the inner rockers for a 2 door merc - pictorial dwg.
PM me your email address and i will email photos to you.

 

they just deadend into the inner fender well, but if that is gone what i just said isn't much help this is a coupe, no pics of a 4door

 

Thanks.... Those pics helped out tremendously.....thanks for all your help
