Will my power brake booster fit when I put my 440 into my 75 duster with schumaker swap mounts?

Will my power brake booster fit when I put my 440 into my 75 duster with schumaker swap mounts? I just finished painting my car and getting ready to reassemble the car. The booster that was on the car had brake fluid leak out of the vacuum hole when I was sanding it for paint I don't think this is common any thoughts? Also will the booster fit with the larger motor?

Thanks
