The Real Gasket just seemed too "fussy" for want of a better word to describe it for me. It had to be 100% clean and torqued to that real low value. The rigid Mopar gasket was just easier to use for me.
I think it's matter of opinion. Seriously, both will work... It's my opinion that the Mopar gasket is easier to use though.
But, I really think all the gasket conversation is moot. How many times have we had these discussions about changing gaskets to clear up leaks when the real culprit is the shifter lever shaft seals almost 100% of the time?
Go under the car with some brake cleaner spray and clean off the area around the shifter and the whole pan area. Now hit the area with some baby powder and run the car a little. (A tip I learned here from someone, I can't remember who). Now you will see where the oil is coming from. Dollars to donuts it's running down the side from the shaft seal and running around the pan.
Once you find it's the shaft seal, go back to my posting where I linked the thread on repairing it from outside the car. The other option is dropping the pan and valve body and remove/replace the shaft seal to the case and the seal on the throttle lever shaft.
