Hello CRG,
I am doing research on dip sticks. I purchased this NOS stick around 1996 - 1998 from Rick George when he operated Rick's 1st Gen Camaro, while I was restoring my Norwood 05A '69 Z28, VIN 638712. I am looking for my original dip stick, as I don't recall if it has a flat or round handle. According to Heartbeat City Camaro (they purchased Rick George's inventory), the green tip sticks they sell now do not have the dimple like the late NOS GM version. My stick does have the dimple in the handle just above the cap seal. This stick states "USE SE ENGINE OIL 3951576 M." The stick measure 19-5/16" from the tip to the top edge of the seal cap.
Does anyone else have the same dip stick with the dimple?
