I have the complete power train of a 1987 S10 Blazer from the flywheel all the way out to the front and rear lugnuts (no wheels) and I have been able to identify the other parts by the numbers stamped on them. However, the front and rear differential numbers do not seem to make a complete match to any thing I have been able to find.
Any body know what these mean?
Thanks.

Do you have the access to the glovebox of what they came in? There is a sticker inside that has rpo's on it.

 

No, the Blazer was involved in an accident years ago which took out the R/H side at the door hinge; repairs included replacing the dash and most of the plastic on that side.
I knew about the sticker location and why it was missing. I'm in contact with the original owner to see if he can find the records he had for it which may take awhile because he said "I know that they are around here somewhere".
It is beginning to look like I may have to just pull the cover and eyeball it.
Thanks for the feedback.
