well i got a new idler and there is no difference between the 2 so i went with cutting and enlarging the notch which was a pain but it works and i also put a 1/4 inch spacer under passenger side and 3/8 under driver side motor mount and now have headers installed, spark plugs back in (wow is that a challenge on middle 2 on passenger side) now working on modifying a couple of spark plug wires and modifiying trans dipstick mount.
