Bellhousing alignment help needed

I thought that once u got it in the exact right spot u would drill two or three 1/8" or 1/4" alignment holes to b able to reposition it during final assembly. You install it then stick a 1/8" or 1/4" rod through the holes and go to town. That way u know you'll have it as close as possible to the right spot?? You could also (once you get the dowels in the right spot) drill and tap a 1/4" set screw into the threads of the dowel to hold it in place (radially). I couldn't find a pic of how stake a dowel pin (using a set screw) to keep it from rotating but I did find a pic of how to "stake". Being a machinist we used to drill and tap the space where the pin meets the casting with a small (1/4") set screw and lock tight to keep the pin from rotating. Once you get your pins rotated into the best possible position you can drill and tap from the back side, install a set screw then you can be sure that the dowel pins will be in the exact correct position when you install the bell.
