OEM Wickerbill Washers

[72 Z27]

For those of you that have installed the GM wickerbill on their spoilers, how many foam/rubber washers does the installation take? 7 or 14?

Do the washers go between the bolt and wickerbill, wickerbill and spoiler, or both? I looked up the GM installation instructions and its vague, nor does it state the quantity that came with the wickerbill.

Thanks for any help.

1 rubber washer between spoiler and wickerbill. 1 rubber washer between wickerbill and metal washer. So 2 rubber washers per mounting hole, 14 total. If that makes sense.
If I’m incorrect then someone will chime in.

That’s how I understand it. But if your going to autoX or track it, I’d highly suggest to put a solid rubber strip that fills gap between spoiler and wickerbill to prevent dust,debris, rocks to get in between that space.

Good luck

I did what SIM did. And I believe my wicker came with like 20 of those foam washers. So yeah, I put two in each. I still have a couple extra lying around if need to replace some
