I had the same problem with my Canton racing oil pan.
Bought the stick that went with the pan and it went straite in to the side of the pan.
not at a angle like it needed to be to get a oil reading. So I tried to use the stock stick
in the front of the engine and it wouldn't pass the screen.
So had to plug the pan and drill the screen for the stock oil dip stick.
I fell like sending canton thier stick back and telling them a thing or two
after a cost of almost 700 bucks in bottom end componets bought from them. Kurt
