IIRC, the taper-wing Cherokees are only different outboard of the fuel tanks. The inboard chunk of the
wings have the same cross-section and thus the same fuel tank geometry. I'm not sure about the taperwing
Arrows, since I think they're 36 gal each or something, rather than 25.

I had the FBO fill up the tanks 5.0 gal at a time after I had to drain them for some reason. Dipped
with a 1/2" wooden dowel and then scratched a line at each position. Very easy, and accurate to within \pm 1/s
gallon. I'll contribute my measurements if interest merits.
