I believe all Astro/Safari vans had the hydroboost except for the first few years. I'm pretty sure from '90 and up would have them. Pull and Save usually has several Astro/Safari vans. I don't remember just where the prop valve is. I'm thinking it is right next to the master. One of my customers is using the Astro master on his pickup. Seems to work fine. Yes you can use a standard pump and just tee the return lines.
Here are some pics and info on the Astro/Safari master in Bubba327's thread

Thanks!
