I had the wrong PN associated with the Block/Clutch Housing Alignment Pins, which has now been corrected to 10067627. Was, right part with wrong PN! Now, right part with right PN :-)

What is the actual dimensions of the dowel you're referencing as 10067627? I was trying to relate the "tale of the tape" to an actual comparison of the 12338119 and it seemed quite close. The 5/8/.625(M15.875) X 1 3/16/1.1875(M30.1625). I paid no attention to the image(solid vs. hollow) only the part # you were using. If a Metric spec I'd expect maybe M16.
The 5/8(.625) is a reference diameter GM used even after engine conversion hardware to Metric spec. for clutch housing. All LS spec through '14 are.
***It might be interesting to confirm bore dimension of a block. Jerry? Anyone?
