These EZ Adjustable Dowel Pins are incredibly easy to use and install.  They slip into the engine block dowel pin holes with ease.  Designed to be turned easily with an open-end wrench.  Once pointed in the proper direction, turn setscrew (which runs down the center of the pin) to tighten and positively lock the dowel in position.  No need to pound the pins in and out trying to adjust correctly.  No drilling, welding or thread tapping required.  Three different offsets are available for each engine so they fit each block correctly.  Plus dowels are longer than stock so block plates can be used.  Fits most 6 and 8 cylinder engines.
