904 dipstick
Why do you need a new dip stick,???. The dip stick will read in the same area as it did before you put on a new deep pan. You could pull it out and put a new "o"-ring on it so it won't leak.
Just for your info,When you install the new Mopar deep pan, I would put on the new style pan gasket from a Mopar Dealer.This new gasket does not come with the deep pan kit. They cost about $12.00 from a dealer.Just ask for one for a 904.They will not leak. Torque the pan bolts to 13Ft lbs. Also when you are filling your new "mopar" deep pan, it will take 7 1/2 qts. of fluid. I use Mopar ATF+3 in all my older cars. Hope this helps.
