sorry, I was not clear: how much distance from tip of trumpet to top of ring?
Damned if I know. Ford specified "centered within 3/16". It's easy to do that. I'll try to measure one tomorrow if you really need a number.
(seen from side). How far out should trumpets go?
As seen from the side, the weld attaching the stainless flare to the steel tube should be directly above the nut at the bottom of the trim ring.
