I have an astrovan hydroboost with a B.C. Broncos bracket. You will have to weld, tap, or replace the input shaft for the hydroboost. See the arrow and you will see what I mean. You can purchase the input shaft from one of the hydroboost fabricators. I went a different direction because I could not bolt the hydroboost bracket to the firewall becuase it hit my efi intake. I had to use the angled bracket. The hydroboost is a junkyard unit that has been wirebrushed and painted. You will notice the blue tape still on the aluminum part. I will ship at cost provided buyer pays.
