Cherokee 140b wing removal.

Hello All,
I have a 1969 Cherokee 140b that is going thru the annual inspection
with a
new A&P this year. The airplane suffered damage the left wing when it
hit a
deer on takeoff in 1972. It was repaired and has flown ever since. The
problem
is the new A&P insists that the wings must be removed and inspected by
him or he
won't sign off on the inspection. He plans on charging me at least
$1500 per
wing. He says it will take about 32 hours per wing for labor. I think
he is
just running up the bill. Is this necessary at all? Should take that
long to
inspect? I'd appreciate any wisdom you guys might share. Thanks
