Hi Tim The first cut is the scary one (no going back!) if you are getting your mesh from Adamesh, I would advise ignore the instructions that suggest using a Jigsaw! The plastic is way to soft / flimsy and would be quite easy to cut in half, much better to use the hacksaw. The lower mesh, behind the plate, is a bit of a Faff, you will get some aluminium blocks to use, to anchor the mesh to the existing grill, again I would advise thread the blocks first with the screws provided, rather than trying to do it while holding the mesh / blocks and a screw driver all at the same time. the screws provided, have very small heads, and will actually pass through the mesh, when you have decided where to place them, use pin nose pliers to squeeze the mesh around the head, or use some very small washers If you can post some pics, and keep us up to date Regards Steve
