M&W aftermarket dipstick, Replaces the oem petcocks. I have one on a SC. I don't use it much and keep it serviced so the clear oil doesn't show up too good. If your going to use it check oil before you start it, otherwise the splash make it hard to read. Yes I shut her down before I check it.
One for sale on ebay was at $99.00 last time I looked.
