1967 DART OWNERS..Brake question

Hello,
I am about to replace my master cylinder.
Car has manual drum brakes.

Does your master cylinder have the M shaped bracket on top to hold down the master cyl fluid lid or does is simply have bolt on top with no bracket?

Parts delaer shows one with no bracket for the 67, my orginal has the bracket so I am wondering which is orginaly correct
