That does not look well, indeed. Who ordered the parts, you or the shop doing the work? Did you check old and new before? I, as many here, was there before and found out strange things about the parts no. of these plastic things. For example, when we did a french 172 declared as being a H version, we found that the plastic parts are a mix of H, but mostly G parts ... the shop knew this before and we spent a fortune on the phone upon ordering to get things right. Yes, fitting the parts in the plane and adjusting the cuts (never never do it on the old parts to more then a coarse first step, always work yourself from the uncut parts to the plane) IS a pain in the a... but this result should have been presented to you by the shop.
