Timing cover interchange

I had a thread strip on the oil feed bolt on the timing cover. Tried to repair with a heli-coil and it went wrong. Long story short looking for a replacement cover. The one on there now has 06-3112 inside. I've seen several for sale that have 06-1072AB. Look very similar except the boss around the points opening is not as thick. Are they interchangable?
