brake booster swap

I am building a frakenstein truck. I mounted a 71 cab to a 03 frame, I have a 01 4 x 4 that i am parting out. I put the 01 stepside bed on the 03 frame. M y question is can i swap the 01 brake booster on to the 71 cab? I want to hook up the ABS and the 01 master wont mate up to the 71 booster, i would appreciate a little help, thanks.

You'd need to check the mounting pattern between the older/newer boosters to determine if it can be done w/o much fuss or if it will take fabrication effort.

The new vs the old might also require a different pedal ratio so you'd need to research what the specs are for each & start from there.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Re: brake booster swap

Thanks, iwas looking at the bolt pattern, but i noticed it will be very close to my shift arm also. I didnt think about pedal ratio. T he bolt pattern for the master is the same, but the recess for the masters are different, the 01 is 5/16 " bigger than the 71. I am leaning towards having it turned down, it would resolve most issues.

Hydroboost. It's worth the effort.

It's all relevant to the application. Hydroboost is great for some (many?) apps.... Not so much on others.
