Didn't know you'd modded the car. You need the stick to go into the rear sump. The front is simply a "room" to house the oilpump, the oil over flows it into the rear in operation, it's not actually a sump per se.
my Lokar stick had a set screw to move the stick in/out of the handle for calibration. the pan I have now is a modded 6 qrt. stock pan. after the mod (for crossmember clearance) the stick still read full with 5 qrts in it. I then added a remote 1 qrt. oil reserve to return it to 6 qrts. it's located behind the driver side headlight in the wheelwell.
