Question:

Hello, I am looking for a replacement part for a Thule Evolution cargo box. I am looking for the U-bolt PN 43215 that is used with the Quick-Snap mounting system. PN 14691. Can you help?

The replacement U-bolt for the Quick Snap hardware is # 43216 which I believe the part number you meant to type in.

I currently bought the wrong U-bolt. After doing some search I was able to come across the actual manual for my THULE Cascade XT Model 677XT and it stated that the U-bolt #43215 is the one for my box. Would you have anything that matches that U-bolt?

@RichardP It looks like Thule unfortunately discontinued the 43215 U-bolt and there isn't a replacement available so your best option would be to pick up new U-bolts from your local hardware store. If you don't still have a U-bolt to measure you can just measure the holes, their spacing and the gauge how much length you'll need to pick out a new U-bolt that will fit. They should also have some compatible knobs with nuts built into them so that you can tighten the U-bolts down, securing the cargo box.
