Brake pedal help for front disc conversion

[derotoreut]

I've searched the forum and can't seem to find an answer to this. I purchased a front disc conversion for my '69 C/20, and I'm stuck with the installation of the push rod. The directions say that for these trucks there are two mounting holes in brake pedal arm, and I should use the lower hole for mounting the push rod. The pedal arm on my truck only has one hole. I seem to remember seeing somewhere on here that people have drilled a lower hole in their pedal arm. Hopefully someone out there has run into this same situation and has some insight for me. Thanks.
