HELP Please: Brake Booster Rod Length?

HELP Please: Brake Booster Rod Length?
Hi all.
So I'm changing out the master cylinder on my 72 Delta 88. The booster seems fine, so I cheaped out and decided to just do the master c. This is probably where I f-ed up...
My new master cylinder looks to be the same, minus bleeder valves at the line connectors. (Never saw that before) However I discovered that the booster push rod is about 1.5 - 2 inches too long. There's not enough threads on the rod to adjust it in.
Any suggestions on what to do? I'm thinking a new booster is probably the smart way to go?
Thoughts? Thanks!

You just got the wrong master cylinder for your booster, probably not your fault.
According to Auto Zone, a 72 88 with a Delco Moraine booster takes a shallow hole in the master cylinder.
If it has a Bendix booster it takes a deep hole in the master cylinder.
Given that information I think you may have a Bendix booster and need a master cylinder for that application. Auto zone number NM1496 is their new unit--- and a reman unit is # M1496, these have the deep hole you need.
I would switch the master cylinder and keep the booster.
Good luck,

Devils advocate here... Could I just buy the correct power booster for the master cylinder that I already bought? Then I'd be new/new.
Confession: I adjusted the push rod all the way in and didn't mark where it was. Yes, I'm an as*hole.
Thoughts???
And THANKS 66lvr

Totally get your point! But my question is, since BOTH styles are listed as correct replacements, can I switch over? Will it bolt up and operate fine. The only difference seems to be the push rod length. And each style has a matching booster.

If my understanding your problem is the push rod between the booster and master cylinder then there are two different lengths on the push rod.
