However, I don't know if the smaller PB issue applies to them or if it's unique to turbo engines in the USA.

Hmmm....has anyone ever measured the PB recess on a 60X engine crank? I wonder if later trannies (ie for the 601, 602, 603...) use a smaller snout on their TC's??
Knowing that the 61X engines were seeing their last days, this might have been a running production change to accomodate follow-on transmission production/manufacture.
