Hi Bjorn, FN419C is the dipstick itself. The one I ordered was FN 419F, but it came in original GM packaging and didn't havean Ames stock number on it. I talked to Ames who said it is supposed to be the same as the one I should have for AC. Guess I'll find out if it clears the AC compressor once I get it all back together.
