Anyone had any luck finding 86 WH1 paint codes?

My boss and his dad are needing to paint new bumper fillers for their WH1 they bought new. I pointed him to the spid on the trunk lid, but the WA.xxxx number is for the black. Nothing for the gray, and they are having a heck of a time matching the gray. Nothing they have found actually matches. They don't want to ruin a perfect, original, low mile WH1 with mismatched paint. I was hoping someone has repainted their WH1 and could maybe give them a lead. Search didn't really turn up any concrete info. Pics of car and their collection for your time.

Check the paint codes on the cowl tag under the hood on the driver's side. It will have the GM 2 digit codes on it.
