MG T-ABC

Hello
today i practiced a bit with freecad and tried to make a technical drawing of the side window frames.
My frames are probably not original

therefore the question how are the dimensions
wants to make a good drawing so that everyone can make their own.
A friend needs some, I can just make them after mine, but will they fit?

the angle of the front bracket ?
the rear one is vertical but the spike is tilted forward

here my first drawing ( one changed )
print it, change the mesurement and i will make a new one

nobody there who has good side windows
and can control and correct my masses ?
Believe that TA and TC have the same mass
