I am pretty sure it doesn't matter what year, but in this case, it is for 1989 and 1990. Both of my engines are together and I cannot seem to find the info I had when I had one apart. as a matter of fact, the early vin L engines should be the same as well. Calculations, based on leftover parts, would put the rod between 6.3" and 6.4", center to center.
