He he, it is funny, I was asking what part of the above... :-)

Kinematic time dilation and space-time oscillations of G. waves
 are not related. The former happens even in perfectly stable flat
 spacetime. OTOH, for g waves time is not dilated.
---------
Nothing happens to  lengths. "I assume thats its purpose?I
 understand that we cant trust our perception of time dilation and
 perceived length of objects.

We know that for most cases the difference is far below the
 resolution of our measurements. Usually , measurements have to be
 specially designed not to be.

It is question of interpretation.
It can be also said the length of time duration is observer
 dependent and that the "real" values for the observer in rest wrt
 measured phenomena is just our convention.
----------
 > However, I had come to the conclusion that the problem with our
 perception is that it cant perceive the physical variation if we
 travel to different environments alongside the object we are
 assessing. 

There are no changes.

Do you think you shrink when I start moving wrt you ?
------------

You have arrived at a different conclusion, that the effects of
 length contraction are not real, but just a product of our
 distorted perception, caused by time dilation. Do I have this
 generally correct?Do you have a simple argument to defend this
 view?

Every good textbook has arguments for that. The key is to realize
 a motion is not absolute.

_--------------------

> I suggested that LIGO's method of detecting gravitational waves relys on Length contraction being a physical effect.

No, it does not.
--------
 Or else there would be no fluctuation in photon frequency caused
 by LIGO's length contracted arms. 

As spacetime oscillates, it would  provide it without kinematic
 time  dilation.
