Hi there! Looks like you need a new tie bar and tie bar guide. The guide is easy, so we'll start there: I recommend our 39-448. The style is slightly different than yours but it should still work. The video below should also be helpful.
I'm less certain about the tie bar itself. Please give me a little more time to look into it and I'll get back to you ASAP.

I think I get what you're saying, Alan. You can snap the tie bar guide onto the tie bar anywhere on the bar. It doesn't necessarily have to come in from the top. Refer to the image below to see what I mean.

Thanks again. Your site and videos are outstanding! The nylon lugs on the locking bar seem ok. I'm going to order the guides and go from there.

Thank you for the compliments, Alan. Once you receive your replacements, make sure to get back in touch with us and let us know how everything works out.
