Pedal Push ROD needed

I kinda scares me when someone is winging a brake swap. Dude, do some reading. I admire your gusto...but get some knowledge first.

The manual pushrod from you 64 is the same for any other A body manual MC. Use it.
If you get a A1-Cardone MC (101627), its comes with a little rubber piece (looks like a 1/4" long length of 1/4" black rubber tubing - - but its NOT - - dims are slightly different). That little retaining rubber is all you need. Lube it a little, then slip it on the pushrod. Tap the pushrod into the back of the piston.
