I know the skinny on this one. .
Call a Cummins distributor an give them the chrysler vin#
Once you give them this, they can convert it to the engine serial number, and send you a paper copy of the fields on the data tag.
Unfortuneately they no longer manufacture the data tags, but will send you a generic model that can be engraved.
The other choice might be to find a 2003-2004 and get the part # off the white vinyl adhesive tag on the engine, perhaps they can run one of those to stick on the gear housing.
I purchased a 98, 12v. that had this issue for my brother. . missing data tag (case prior to us buying the truck) the tech was too lazy to swap them over. . the least they could have done was to grind the rivets and return the data plate to the glove box!
The part # 3926850 (superceeds but no longer manu. ). . this is what was on your truck.
Generic blank plate=3027288.
I don't have the number for the rivets handy. . sorry
Hope this helps, if you find out the originals are available pls. let me know. I/my local research specialist have spent hrs on this. .
