It was just sort of my understanding that the dual sump pans with the oil dipstick hole in the pan were kind of harder to find.
There's a Ford racing kit with a dual sump foxbody pan, that timing cover above, and the dipstick w/ tube (and some other parts). The 80's dual sump pans are a dime a dozen. But essentially, it's a dipstick tube to work with timing covers with dipstick provision that are using a foxbody pan.
I have the kit minus the timing cover, I bought it cheap for the pan, pickup tube, and reverse flow water pump. My old pan was pretty rusty under the paint and I am converting to reverse flow with a different timing cover. I am using the stock location in the block for dipstick.
I have no intentions of using the dipstick or tube, but it is brand new. I have no clue if it would fit, but would work in theory. I would be willing to sell it pretty cheap. Also can take pics and measurments.
Here's the kit I am referring to:
