Bigger tank for early Arrow

I wasn't aware of the 235 wings being that much different (had never
pursued it, though, either).

The 235 is nearly as different from other Cherokees as the Cessna 182 is
from the 172.

In addition to the 6 cylinders and constant speed prop, there are lots of
thicker skins throughout, to take the extra horsepower and weight. Also it
has a much different fuel system, and all sorts of extra structural
cross-members.

Hmm, those twin-tank setups are on Senecas too. What I think would be the
"ultimate" solution would be to transplant the Arrow III (37 gal) tank
to the Cherokee 180 (or the straight-wing 180 and 200 Arrow). I actually
measured this, and it would fit. The outer end of the tank is one wing
"bay" longer on the 37 Gal tank. There is already a rib in the proper
position. The operation would be (1) remove old tank (2) cut wing skin
one bay further out (3) remove rib thus exposed, replacing it with the
old outer rib (4 - and this one is dicey) re-drill spar to take screws
in the extended tank area (5) put in new tank.

Before I start spending $1000s that I don't have, I should stop!
