Pretty easy to make your own...I did. Use brake line, 5/16 or 3/8 I forget which one fits the dip stick just right. then get the flare fitting for the size hole in the
oil pan. Run the line anywhere you want up the side of the engine. Put the dip stick in, and put the right amount of
oil in. Then just look at the dip stick and mark the
oil level, so you know where full is. After brake is bent to where you want it, and you cut it to length, the dip stick fits perfectly.
