My parts catalog only covers the straight wings up to 1973. The models
of PA-28-140, 160, 180, 235 and PA-28R-180, 200 all use the same part
numbers for their fuel tanks. P/N 63998-16 for the left and 63998-17
for the right.

Thanks, but I'd already seen that. My concern was that the tanks on
straight-wing Cherokees might have a different x-section. Cory Pappenfuss
replied on the other thread that the tanks are probably the same. I will
ask our A&P if the tanks use the same part number. That would clinch it.
