Brake booster / master cylinder question

[stabbyjoe]

Okay, without having to pull mine apart and check. Does anyone have a measurement for the stock brake booster pushrod to the MC? I'm going to be putting an 2500/3500 MC on as my replacment. when I do, I will need to extend the pushrod by about an inch. I was hoping to have an idea of what size bolt to have on hand. I know the thread pitch but cannot track down a written length for it.
I do understand there is "no benefit unless" you have bigger piston and bore calipers that ultimately allow for flow/pressure but in preparation for the big brake upgrade and Vanco setup im doing this as my master cylinder needs replacing.

Chances are you won't find the length you need so buy a bolt and just cut it to the length required.

That's what I plan on doing, hence why I'm trying to find the stock length. I. Going to buy a bolt 1½ inches longer than stock cut the head off make to approximate size so when i pull it apart i make little adjustments and im good to go. I just need the stock length to do that before I have it torn apart. That's all I'm hoping for.
