Is there a difference between 26-7 then a 25 back danuser88@ktis.net
26-7 have "wings" that stick up on each side for fender mount
The wings on a 26 27 are not part of the cross member. The actual cross member may be the same.

the TT crossmember is different.
the frame channel is taller at the front on a TT,
and because of that the crossmember has less drop.
That keeps the front motor mount at the same height on a TT as a T
I hope that makes sense.
I don't understand the question. Is this about the front, or the back? And just what is the question about whichever it is?
Steve,
The post title says, "front crossmember on a T". Then question is, "Is there a difference between 26-7 then a 25 back".
Well, yes. There's a big difference between a 26-27 front and a 25 back.
I think "25 back" means 1925 and earlier frames.
I could not see any difference in the 25 and 26/7 front cross members. The front was lowered an inch in 26 but that was in the spindle and spring arch. The back cross members were changed in 26.

The #2853 front cross member for the T is the same.
The Improved car got brackets riveted to the ends for the front fenders.
In Dec 1920 the cross member began to be made with a heavier guage steel, so the early ones are thinner than the later.
The heavier gauge also has the Ford logo, which the earlier version did not.
Thanks everyone as my small stroke I had in March screwed w/my thinker
Peter, the TT front X member is exactly the same as the cars. It has the exact same factory number.
The measurements are all the same until you get into the last few years when it was made 1/4 inch shorter to compensate for the stresses bending it downward trying to pull the Radiator apart. The engine mounting position used in the TT is the same as the cars being mounted on the top of the frame rails. The TT frame is just deeper through the center of the frame on the bottom side.
Dan, the only difference added to this X member was to the 26/27 cars were the ears that were riveted on to extended this X member to hold the New improved fenders.

The T & TT crossmembers may have the same part #, but they measure different.
I just went out & measured a T frame & a TT frame.
On the T frame the channel at the front crossmember is 2" high & the crossmember is 3" deep giving a 5" dimension down to the center of the crossmember/motor mount pad area.
On the TT frame the channel is 2 1/2" high at the front crossmember & the crossmember has a 2 1/2" drop giving a 5" dimension down to the center of the crossmember/motor mount pad.
TT crossmsmber has 1/2 " less drop that a T crossmember.
This is going by measurements from really nice samples.
I learned this the hard way once when replacing a front crossmember. A TT crossmember in a T frame makes big problems between the bottom of the radiator & the top of the motor mount !!
Thanks Fred, on the brackets for the Improved Car, yes they hold the fenders to the front cross member.
As for the TT, the front cross member is Part #1122, and the T Part #2853 is front cross member for the passenger car. Different part numbers.
Yes Dan the Part numbers are different and if you have the parts books that shows the Factory numbers it shows that Ford used the same number for both "303". I have placed some of these X members side by side and they look to be same size, width, thickness ect..
Seems to me there was a weird thread a few years ago on this.
Peter,
I can relate to your last comment regarding the differences in the cross members. When I restored our Fordor 25 years ago I made the same mistake. I didn't discover the problem until I tried to fit the radiator.
Regards, John

There is a difference.
The truck front cross member is Part #1122, and the Factory # is TT-303. Description is front member- Truck '18-'27.
The car is Part #2853 and Factory # T-303.
Respectfully
Dan
