I'm ready to start my UD installation this morning and after watching the installation video I realize that I do not have the water pump bolt that is needed to replace the stud and nut that will now hit the water pump pulley.
what kind of pulleys did you get? who has a video? you can trim the non threaded edge of that stud off with a hacksaw blade. you dont even need to get into the threaded portion of the stud. the roush pulleys say to trim rather than replace.
but, i think it is an 8mm bolt, 1.25 thread pitch, 50 mm long.
click the link in my sig for everything you need to know.
The hacksaw should work fine, although my Steeda kit had the replacement bolt, it's already on, so I can't really measure it. You should talk to Brenspeed about that bolt.
The puller you need seems to be refered to as a Chrylser pulley puller, at Autozone it's something like #27139 on their tool rental list.
