Transmission gap

[chevymike]

Just for the record. Not all CUCV's have the HD cast in the case. I have seen many without the HD embossed. And I have matched the numbers to the vehicle. The last 8 are stamped on the side of the bell and they matched with NO HD in the casting. I see no rhyme or reason for this. Your example my be correct. Good Luck.

This was the correct last numbers of my VIN. Not sure where the cutoff and what is what here. I seen it many times with and without.

Yeah, gotta love GM. Hit and miss sometimes on things. I do think all true 4x4 trans cases have the thicker cover flange and the 3 threaded bolt bosses on each side. This is to help keep the case from cracking (when using the correct cast cover) from the extra leverage of the transfer case.
