Rear ones are no problem (in fact I have a couple sitting in a drawer).
Front ones are not possible as far as I am aware ... if you go and look closely at where they end up, you''ll see that they follow the contour of the wheel liner and curve slightly inwards towards the front wheels.
But if you find a solution please share.

Cause you either posted in the wrong section or I gave you irrelevant advice ... or both.
