Welcome to the HAMB. You might want to do an introduction. As to the question, it depends on what you have and what to want to do with it. A 1925 T is going to fit a T frame. Those are designed for rough or no roads and low speeds. If you want a faster, lower car, you have lots of ways to go hot rodding it, but most modifications are going to require some planning and modifications to that body, if it's in good shape. If it's a typical 100 year old body with decades of rust and damage, you need to fix it too. Those also have wood framing, which almost always requires repair or replacement. A T bucket frame usually has a step in the rear that does NOT fit a stock body. What are your plans for the project?
If you're not using a Stock T frame no matter what or who's frame you choose you will need to make it fit. The other side of this is to build your own to fit your needs. Building a T frame is about as simple a project you can get into. If you can't build your own, you will sure have your hands full making it all come together.
It all depends on what you want to do. A good example is the 1/8 scale model T (model car) that was sold by Lindberg Line. The basic kit came in two versions. One was as a roadster, the other was a coupe.
