Hello, I have an MC120.2 that needs an upper grill replaced - the fabric is torn. I tried taking off the trim based on what I saw on a post a couple years ago and couldn't figure out how to do it without breaking it. Now I have the opportunity to buy a parts only S45 (the last version) with the 2 split grills in great shape for cheap and see that the width of the S45 and MC120 speakers are the same. So would the upper Grills be interchangeable? Thanks
