Power steering box help.(1968 Barracuda)

Hi all, Just wondering what everyone is doing for power steering boxes these days.
I installed a new rebuild from a Mopar parts company 2 years ago and it is puking fluid big time!
A sloppy steering wheel fluid puking piece of crap! I picked up a 1968 factory box that needs rebuilt. Some advice whether you have had yours rebuilt or something new,aftermarket that works well.
Thank you in advance!
