Hydroboost anyone using stock PS pump?

20 years ago I swapped a Cummins Turbodiesel into my 75 Dodge B300 van. Because of the radiator I used there was no room left for the van's original vacuum brake booster. I ended up using a hydroboost from a Chevy P30 van. I used the stock Saginaw pump that came on the diesel. It worked just fine for the 3 years/35,000 miles the van was on the road.
