Q3 Jack problem ???

[GT3Pete]

Hi everyone,

I was in the process of removing the wheels to clean and finish with Rim Wax. Front offside no probs, but when I came to the offside rear, I find the inner arm of the scissor jack fouls the plastic cover covering the floor pan before the jack is located in the jacking point,

Do I carry on hoping the plastic cover won`t split, or buy a trolley jack ????

Tried posting pics, but nothing happens when I click upload an image ????
