hello could you give me any information on modifying EF Ford twin themo fans to fit a VP 1992 radiator because i want to upgrade my fan and need to know how to modify the fans to suit because some places say they fit and some say they dont and i just wonder. so do you have to rewire the whole fan system to work non holden twin and single fans, vt twin fans, vs fans or ef twin fans or can you just plug non holdens or later holdens into the existing vp radiator fam wiring.
