"And for your information, the grills are different to..... Joe"
I found this out the hard way a few years back when I came across an original grill at a swap meet. Although only about a 6 (out of 10), I figured it as a good "hole-filler"....
I was wrong!
It almost fit, but dimensionally wrong so it was unusable. I think I still have it around here....somewhere!
