Previous owner of my A66 put the SE finish panel on mine too.

While it might look good it wasn't correct so I posted an ad here & it sold within a week. It was an NOS piece when installed IIRC.

If you happen to do the same, large diameter PVC pipe. Mine was sewer (clean) pipe. I had to buy a full length piece & it was like $40 but well worth it.

Really nice color combo.
