23 Honeycomb will not fit an R. I modified mine, but it was lot of work.First time poster here, but trying to locate a non modular style (honeycomb) or similar lower insert for 24R. Installed the SPV lower 10” LB kit and not liking the OEM insert going back in. Can’t tell if the 23 honeycomb style will work, due to the slashed angles where it meets the side covers.
