Just to close this out:
After a 1-hr wait I got to talk to WBGO customer support. They said that, when they get ill-fitting parts like this out in the shop they just trim to fit as best they can. So, that's what I will do. It sure ain't gonna look like factory.
Evidently, their receiving/inspection folks just ck to make sure the product is the right color? Hmmm ..... maybe they don't do receiving/inspection.
BTW- With shipping, the 2 mats were approx $80. GREAT quality material; the fit.........not so much.
Good weekend to ya. Ed S.
