Brake booster pin/pushrod adjustment

I recently installed a new AC Delco master cylinder and now my brake pedal feels low and a bit spongy. Is there an adjustment to be made on the pin in the booster for correct length? I can find nothing on the search feature, and nothing on Google other than generic how-to's. TIA

There is no adjustment. GM service manual talks about a service part that is adjustable but good luck finding one.
