Please let me know if you sell the plastic guide and the item number for it. If you don't sell the plastic piece by itself, please let me know which is the replacement item number for it. Thanks.

Thanks for posting. I'm afraid the plastic part of this guide is not sold separately, but see our 23-090. Look over the dimensions and see if you think this is what you need.
