As mentioned above, these are original (I buffed them up), and yes they require a bit of straightening.

I'll check the measurements for a start tonight.

Not sure in this case grinding and buffing will work, as it would have to be the visible top portion, not sure if under the chrome the pot metal will buff up? I suppose one could rechrome them.

That's why I thought this was odd, NOS gills, NOS orig sheet metal, does not compute!

I actually did test fit most items. Even these and had noted them as an odd fit, but that particular issue got lost in the melee.
