I just picked up a 2002 Durango 4.7 with a bad motor. I just removed the motor the other day and I am looking for a new one but every place I call asks me if I have a 16 or 32 tooth tone ring. From the research I did on this site I think have the 32t tone ring but I just want to make sure before I buy my motor tomorrow. How can I be 100% certain that I have a 32t tone ring? Another question I am asked is if I have a Fr carrier mtg. (not sure what they mean by carrier mount).
