Keep the dipstick relevant to the sump, measure the length of the tube that sticks out from the block, then measure the length of the dipstick itself from the collar that sits in the tube to the min and max markings, then do a search as I posted up these measurements not so long back, doesn't matter what one you use so long as it fits and keeps oil level somewhere near, I always run mine around 1 1/2 pint over anyway.
