confirmation of channel replacements

Question

I need to replace a total of 18 channels, of three different sizes. I believe I have figured out what I need, but I would like to be sure. Attached are some pics of the top and bottom pieces. The top piece appears to be 19-005 and the bottom looks like 15-005. Would you agree ? Measurements all seem to match

If your measurements match the nylon guides you mentioned, then our Series 380 looks like a great match. I cannot really confirm based on just pictures, though. The only way to know is to match up your dimensions to ours.
