Disc brake conversion

[me71c10]

Hi there hoping for some advise. Im doing a power disc brake conversion on my 68 C10. I have a few questions that i cant find answers for by doing a search and my instructions are vague.

1) How do you remove and then put back the brake pedal clevis pin? I was able to pry old one out but have had no luck installing new one. The steering column seems to not allow bolt to slide in. Any secrets? Its stumping me.

2) My pedal assy only has one hole for the manual set up. Do i use that hole?

3) I adjusted my rod length to that of the removed manual push rod. Is this correct?

Thanks. Trying to move forward while we are all self distancing and this has stopped me from proceeding.

Have a nice Sunday
