I have this real deal original flat handle yellow tipped dipstick up for auction on Ebay. The auction started at $9.99 and has no reserve. This dipstick is a real deal production line installed part and is very hard to find. I believe this was used on 1968-1970 applications. Later dipsticks have different wording on the stick.
Here is a link to the listing:

I also have a bunch of other NO RESERVE items in my other auctions including more parts off the same 1969 high horse 427.
Thanks and good luck,
Jason
