What dipstick? Milidon pan

I run the rear deep sump milidon pan made for a 4x4 on my 440. I cant find a dipstick made to screw in the fitting on the pan?

A few years back I put a 440 in my pick up truck and the donor dip stick tube was mangled too bad to use. I made one out of 3/8" tube (brake line I think). I was going to have to "adjust" it anyway with headers, just easier to start from scratch. Dipstick itself, I used one from a old Detriot diesel truck and cut to fit.
