There is also the outer diameter to consider, depending on the crank being used.
The 4.2L crank was different from the 4.0L crank. This comes into play when doing a stroker on a 4.0L motor, which uses the 4.2L crank. I messed with all this when I did my stroker. Now, where are my notes.....

4.2L Engine
ID: 0.580”
OD: 1.056”
P/N PB122
1995 Cherokee 4.0L Engine
ID: 0.755”
OD: 1.001”
P/N PB207
Used for me:
ID: 0.755”
OD: 1.055”
P/N PB 117
4.2 L Crank used a bushing (or bearing) that is 1.056” diameter
4.0 L Crank uses bushing that is 1.001” in diameter
Early AX-15 transmissions have a input shaft that is 0.580” in diameter
Later (1992?) AX-15 transmissions have an input shaft that is 0.755” in diameter
So, stroker in a later model AX-15 would use PB 117. Stroker in an earlier model AX-15 would use PB 122.
Hopefully, this helps, and doesn't just make it more confusing.
