Default Pontiac Bonneville Sunroof Shuttles

2000 Pontiac Bonneville SE

Hello everyone, I have been slowly diagnosing my sunroof problem (Won't open backward, roof will, however, pop-up) over the last few weeks, so far this is what I have done.

1. Removed headliner
2. Removed Sunroof glass
3. Removed sunroof track
4. Plugged in sunroof track outside of vehicle to diagnose problem.
5. Found (2) Broken Plastic Shuttles
6. Noticed that (2) other plastic shuttles were cracked.
7. Drilled rivets on track to expose the broken shuttles

So, I have found out what the issue is. It is the shuttles that pull the sunroof open and closed, Now, I can pull the sunroof open after releasing the risers on the assembly, I can then pull the supports back (like the roof was opening) and then i can close the entire assembly with the motor itself, however, since the shuttle is cracked toward the back on both sides, it is impossible to open with the motor, only close it. (However I can, after actuating the sunroof all the way back, pull the supports back by hand, and they will close with the actuation of the motor. My question is if anyone has any idea where I would go about purchasing the shuttles to replace them. Also the guide linkage shuttles have cracked off. So, I am in need of 4 total shuttles. I have called around, and all of the salvage yards that have them require the purchase of the entire assembly which they are asking a min of $250 for, but all i need are these small plastic pieces and have no need for the glass, guides, motor, etc. I posted pictures of both shuttles below. Its kinda sad if I have to purchase this whole assembly, because these pieces are so small and look extremely fragile. After looking through the forum for hours, I have seen a few instances where people are having the same issues. Let me know what you guys think. Thanks in advance everyone!
