Thanks for the replies. I'll check it out again when I get a chance later today but I'm pretty sure the dowel holes in the bellhousing that I have aren't open unless I'm making a mistake and using the wrong holes.
@66Valiant528 you're saying the slotted end goes into the bellhousing? I thought the point of the slotted end was to be able to expand to keep the dowel held in place in the block when you drive the hex head screw in? Seems as if every video I've seen shows the slotted end going into the block with the other end being stamped on the end to show you which way to turn them.
