The part number is P5153643. It fits with no problem lots of clearance. I never tried the factory dip stick i just used the one that came with the pan.Since then i have used the Milodon twice and it fits the same. Except it uses a factory dip stick on the driver side of the block. We ended up using a dipstick from a 2005 Grand Cherokee. You can see the handle in the pic. The pan is about 1/4" above the K Frame.
