Replacing Master Cylinder

Matt Miller said
Can someone post a photo of the correct master cylinder that would be found on a 70 Dart Swinger 340
Front Disc Rear Drum manual brakes?

Thanks
Matt

This is what I purchased for mine. I believe it is a 71-72 MC but will work for my front disc rear drum on my 1970 Swinger. You will notice the larger reservoir for the front disc system.
