Mike, that is even worse.
What I do not understand is why is the LT so wide, they are supposed to have a 6.5" Gullet.
You mentioned a 7.25" Gullet and a 7.5" Gullet, those are Narrow Draft and/or Extra Wide QH Trees.
Of course when they line the bottom of the bars with leather and fleece that will raise the clearance a little bit, bit no way can those tees even come close to working, why they are starting off with 2-3 sizes too wide of a Gullet sized sample tree is very confusing to me......
From the original fit forms you posted a while back, the LT and J forms looked the closest to me, both have 6.5" Gullets normally and steep rafter angles.
I would suggest going back to the saddle maker and asking for the trees that are more in line with the Standards that Steele makes, not these Trees that have had 3/4 of an Inch added to the standard Gullet size......
