I know that the gears are bad, but I wanted to know is it a Trac-loc and will it fit in a 489 case?
It is in a 741 know. And yes what is up with the heat mark?
Trac-Lock is a Ford term. There is no such thing as. 8.75 trac-loc . Therefore the answer to your question is no, you do not have a "Trac-Loc" and no a Ford Trac-Loc will not fit in your Chrysler 8.75
