4000S to 4000 quattro?

[Tim Sexton]

Hello All,
    Does anyone know if one can put the drivetrain from an 86 4000q into
an 86 4000s?  Is the body tub different in the 4000S?  I have found a
43000 mile 86 4000s that would be a much nicer donor car for my 4000tq
project than my current 194000 mile 86 4000csq, but if I couldn't make
it a quatto I can't use it.
Thanks,
Tim Sexton
