Replace white regulator slider clips only or entire window regulator?

[squidzilla]

Hello all.

I came out to my auto X to find my rear driver side window down. First I thought I might have pressed my key and somehow got only one window to go down. Nope. The regulator clip is broken. I found small piece inside the door.

I have taped it up with some duct tape while I order some parts. The dealer only has the entire regulator and ebay has white clips.

Have any of you just replaced the white clips on rear? It is not much more for the entire regulator using furious method.com

Since I do not use the auto more than 1k -2k miles max, I really want to do what is easiest and fastest.

I have already taken off the door panel and removed the insulation panel thing.

Thanks.
