Thanks guys. I guess seeing what either transmission looked like complete would have been really helpful
I for sure have the dowel pin on the drivers side of the engine, but its possible I don't on the other... That could be what goes in that place I thought a really small bolt would go through on the opposite side.
The car came with a starter sitting in the trunk, I can only assume its an 02 WRX but I suppose it's possible it could be the SVX one.
