Note that the very last of the B20s and all the B30s used the same seal.
You need to center it up (I have a plate that I bolt them and the rear
main seal housing to that gets chucked in the lathe) and bore it to
about 2.680". I bore them all the way through. This is bigger than
the biggest part of the bore. I understand that there is a seal
available that will fit into the original bore, smaller than the
B30 front seal, but I have never seen one.
The rear main seal housing bore is 4.334".
