Cardone Brake Booster question

[tomfg]

I have the Cardone 50-3715 dual master / booster combo to convert my 64 to power brakes, (like the one in the attached photo) and I'm about to the point where I have to figure out how to modify the "booster to brake pedal" rod.

Does the rods come out of the Cardone boosters so it could be easily modified? I didn't want to pull it out and damage the diaphram, or not be able to get it back together.

The end of the rod in the new booster has a hole for a pin, but I don't
think I could hook up the old and new rod with a pin in the middle, as the rod would likely flex up when the brake pedal is applied.

I would like to remove the rod from the Cardone booster, cut the end off, thread the rod, and do the same to a portion of the old rod, and couple them together.

Thanks for any help!
