I do have that information written down so I'll get that tomorrow, I did however find some part numbers and sizes ( two are listed) in the parts catalog. 3707389 - 2 5/8" ID and 3739112 - 2 25/32" ID. The last one is listed as pass. corv. not sure what corv. is... in section 5.819 - 5.830
Those two numbers you listed are for Passenger cars and
Corvettes, not a 6100 truck.
This may help. See the attached screenshot with the red box. Those dimensions seem to be close to a -150 size.
