94 Sierra 1500 PS pump in 68 C10

[Berlinvet]

Good Morning Y'all,

I have a 68 C10 LB and recently switched my 350 to a serpentine system taken from a 94 GMC 1500 donor. Most everything bolted up nicely, just need to wire the alternator and hook up the PS pump. The new PS pump appears to have a different fitting than the old one, it is smaller. Does anyone know what line I need to connect this pump meant for a 94 Sierra to my existing box?

Thanks from San Antonio.
