    Difference between 4A frames and TR6 frames?

    I think this was discussed before but would a TR4A body fit on a TR6 frame?

    Or, for that matter, would a TR6 body fit a TR4 or 4A (solid axle) chassis?

    Don't know the answer to those two questions, but I do know that's it's possible to put a TR3 on a TR6 frame as Randy Schultz did...

    No problem, just add a half foot or so to the middle of the body. Tom
    1960 TR3A TS73117 (under restoration year 6, owned since 1964)
    1959 TR3A TS58023 (in case I never finish the one above)
    1969 Triumph Herald 13/60 (a whim)
    1973 Buick Apollo (was Dad's car)

    I have been reading (I know, I shouldn't do that!), and found that the factory actually built 3 prototype cars that were TR3 body on TR4 frame. They made up the difference by moving the outriggers inward an inch, and they adjusted the body with wider wings. So they took up the extra 2 inches with the bolt on wings, rather than adjusting the middle of the body.

    It can be done. Most common is using TR6 frame under a TR250 tub. There are motor mounts issues with going to 4cyl but a little welding will fix that.

    I have a powder coated TR6 frame that I'll be using for a TR250 clone with a 4a body when I get around to it. It's very close to identical with the exception of the motor mounts and a few additional braces that shouldn't present a problem.
