Aluminum master cylinder questions-Early A

Do you have 4 posts or 2 ther now?I,ve use the cast 4 post(dual cyl.)old style 73up with the original pushrod from single master.For the aluminum dual post(I used from a newer Dakota)you can buy an adapter plate 4 to 2 post.You might have to adjust your peddle stop for tailights.I now have a 2 post mounted on the top 2 posts and modified an ajustable pushrod for my application(with fenderwell hedders)So yes it can be done.Pic of my 66 Dart
