i have already put wire mesh in the oval and would like to complete the look with adding it the the bottom grill and the rear grill. So far i took out the bottom mesh but not sure how i should tackle the job. My intensions were to cut out the plastic cross hatches and use the frame for the wire mesh. The plastic is pretty flexible once you get it out. And now that i got it out, im afraid if i cut the cross hatches the fame will not hold its shape leaving a messy install job.

So i was wondering, for those that have do this, do you have any suggestions for me? I thought meshing the bottom grill was going to be just as straight forward as doing the oval.
