There is a 12V motor that comes from most vendors, O'Reilly's, NAPA, Autozone...It fits well but end of motor is shorter and flat so the part that sticks through firewall is a little different looking. it has a slip on collar over drive shaft so it can be used in the stock squirrel cage fans. I bought from O'Reillys years ago for $31. O'Reilly auto Part # PM354 for $31 https://www.oreillyauto.com/detail/...998-chevrolet-venture?q=pm-354&pos=0
