Default Output rod from hydro boost to mc

So I just figured out my brakes aren't engaging because the output pushrod from my hydroboost is roughly 1/2 too short. The rod is just about 3.20in long. I guess my question is, has anyone else delt with this? Are there adjustable pushrods? Do I make a spacer? Or is it better to make a different rod? I'm running an astro van booster with a will wood 1 1/8 master

I ended up making a spacer. I had a piece of aluminum that was the right diameter and just drilled the input end to accept the pushrod from the hydro boost unit. Worked perfectly. Was more than 1/2 inch long though.

What side did you put the spacer in? The Mc or hydroboost side?

Put it in the master cylinder, I've done it before, works good.
