Model T Ford Forum: Forum 2014: New TT project

I am starting a new project…building a TT from accumulated parts. I am starting with the chassis, particularly the front end. I have one complete, restored 1925 TT which I am using for a model. There has been discussion that the TT has a different front cross member..particularly being taller for the thicker spring pack. Then the spring is supposed to have more leaves, too. With the increased thickness of the spring pack, then the clamp/motor mount is different too…longer screws. So, I am trying to put this all together. Here are the details:
1. Of the three frames TT I have, early and late, all front cross members are the same with the same depth of +/- 2 inches.
2. All frames have the same spring clamp/motor mount which is the same as passenger cars…9/16-18 threaded stud/screw.
3. I have a loose spring clamp/motor mount which is beefier and has 5/8-18 threaded stud/ screws which are longer and along with what would be a valence/apron mount screw provision. Can someone please sort this all out for me. Which is correct for an early TT and then the late TT. Did they use a different * motor mount bracket* and cross member?
What did the spring look like? Photos welcomed.

crossmember
Frame on '22 TT with original spring, mount
axle spring
Front axle with 10 leaf spring...should be 9 according to information
Mounts
Photo of two mounts, standard TT and passenger and a *later* heavier version to accommodate thicker spring.

John, see pages 51-55 in the 8-5-28 parts book. Only parts specifically for the TT are listed.

Steve,
Thanks...perhaps I should have a parts book. However the book does not seem to give any details except the years used. I sense that the big TT frame/chassis changes were made in '26-'27 and that the earlier front ends on TTs were basically the same as passenger cars. Except I wonder why the perch seems unique. I think I have resolved this issue. My TT will be pre '26.
John

OK, now I have a copy of the TT parts list and I still don't know what real changes were made to the TT. Apparently the front spring changed in 1926-27, but there is no reference to the front cross member. Is it the same or does it accommodate the 9-leaf spring, along with the beefier clip? There must be somebody out there with a late TT with photos. Where are all the TT enthusiasts and all the background?

John, I have what I believe to be a smaller style earlier TT front mount on my T Touring/pickup. My Touring Cut Off is kinda a hodge podge of parts, never could figure out why they had extra nuts as spacers for mounting the leaf spring, until I found out there was a truck mount. My car is mostly early to mid twenties black era parts.

John, there was a thread not to long ago titled "show off your TT's" where TT owners came out of the woodwork to post pics. You may glean some info from those pics. Possibly even PM some of those owners with specific questions if you don't get answers here.

Gary,
Thanks, but I effectively initiated that thread, thanks to Burger...and I truly appreciated the participation. Perhaps I can find the appropriate photo and address the owner.

Here is the mount on my TT chassis. I believe this to be about a 1925 but some parts are mismatched. I now see that my front mount is not correct for the TT since the ends of the studs don't extend through the castle nuts. The outer U-bolts are fine though. I have no idea what this triple mount is from originally.

Justin - I think your triple mount front spring clamp is an after market accessory. I think one like this was posted on the Forum some time ago.

If I ever get mine running, I think I'm going to remove a couple leaves from the rear and put standard car springs in the front... I'll be driving on modern roads without a heavy load, so I think a bit smoother ride will help add to the enjoyment of it.

I never really thought about it being an accessory. I'll search for the old thread. Since the subject of this is up, I would be interested in a TT center mount just so that I can get cotter pins in all of the studs if anyone has one available.

On the subject of the original post, I can't shed any light on the subject of what is correct for an early/late TT chassis.

Justin,
Thank you for your interesting contribution. Not sure what to say...I am still looking for details of the production cross member/clip/spring, etc...particularly for '26-'27 which seem to be peculiar. What is different about the '18-'27 cross member as listed in the parts list?
