Lokar transmission dipstick funnel

[dickeymoore]

I have a 700 R4 brand-new that I will be installing in my G body with new torque converter and I also have a lokar flexible dipstick my question is is there a funnel that will fit the flexible dipstick without using the little dipstick funnel adapter that comes with the dipstick

I will have to add at least 15 quarts to this transmission
