Are the 66 rear speaker grills oval or rectangular? Thanks.

Both of my 66 nos rear speaker kits are rectangular.

Thanks, just trying to finish up my interior and my car originaly came with a rear speaker. A guy had a rear speaker kit for sale on E-Bay with a rectangular grill. He thought that the 65-66 grills were oval and the 67-69 were rectangular. The one he had for sale which was advertized as NOS had a retangular grill and was advertized as for a 69 car.
