helicoil or similar for blind hole?

Hi all,

I have a thermostatic fan clutch that I'd like to use on my old Studebaker, but one of the holes where the fan bolts on is stripped. I am hesitant to drill any farther into the housing to make the repair, and am wondering how one deals with this situation where one can't run a tap all the way through. If I were to take a Helicoil tap and cut the end off to make a bottoming tap would that work? How do you break off the little tang in this instance? Or is there a better product for what I'm trying to do? (Timeserts? but where do you actually buy them? only place I've seen them used is on old Porsches...)

thanks,

nate
