I have a June 92 Mighty Max with the 2.4.

What are some ways I can difinitively tell if I have a 6 or 7 bolt wideblock or narrow block without taking the engine apart? I would use this chart:

But the problem is that my truck was built during the time period that they switched from the 6 to the 7.
