Manual Brake push rod needed

Great! Thanks Fastfish66. I am converting over from drum to disc on the front, but staying with manual brakes instead of going to power brakes, and I thought I would have to change the pushrod. Instead, I'll just switch the master cylinder for a drum/disc one (reservoirs different sizes) instead of the drum/drum one I have now (reservoirs the same size) - unless I am mistaken, it should match up to the 4 bolts already there and it will work fine?
