I purchased this item based on the reviews here at Amazon. I was excited about FINALLY finding a tool that would help me remove the dang oil cartridge cap. Long story short (and after a lot of frustration): This item is TOO SMALL for my 2008 Tundra Crewmax, I can't speak for other models. Went to AutoZone and they don't sell the part, which is why I turned to Amazon. Now I'm going to have to purchase the item from Toyota themselves...sigh.
