I have a DSS main girdle and oil pan. They told me that I could use my factory dip stick I would just have to bend the tube alittle so the dipstick would go past the girdle. If I bend it enough to go past it the dipstick want slide through. I even bought a different dip stick and tried that one and no luck. Am I the only one that this kind of @#$% happens to?????This is I would call DSS but they arent opened on the weekends.
