2000 Toyota Sienna Rear Blinker Assembly Clips Broke Off

Considering your comments, my suggestion to you is to replace the assembly. If you still have the pins, you could possible repair the assemply by using some (possibly) super glue or maybe even some epoxy. This approach, while cheaper, will never be as strong as new, as well as it may not align correctly once completed.

As a cost saving approach in lieu of purchasing a new assembly, you could alternatively try a wrecking yard or even look for part-outs on Craigslist. This may save you a few dollars in the end. These assemblies new from the dealership (affectionately called a "stealership") can be extremely pricey.
