Some years back my late buddy Bubba put one of those in a '39 coupe. No pics, but I gotta say, it just never looked good to my eye. If you like the crisp line of a V-butt execution, the soft bulge look that these give probably won't appeal. It's not a uniform arch, looks more pronounced at the top and bottom. Surprisingly it didn't give any annoying distortion from the inside as might be expected, but outside...........................looked like a wart on a nose...............
