Front Spoiler 69 cars

[LM69Z28]

We are currently running the standard repro front hardware spoiler kit (original spoiler car). Does anyone make or can someone suggest a more correct mounting hardware set that includes correct bolts, nuts washer etc. as shown in the AIM D80 A1 section. I am sure the existing brackets will still work fine.
Thanks for the help
