<VV> early defrost tube fix

[Smitty]

Smitty Says;   The defrost tube in the forward part of Early convertibles is 
made of a fairly thin un coated metal.  Stampings form a duct and route it 
through the inner section of the two part rocker assy outboard and up.  It 
goes forward to just ahead of the floor vent and then passes through the web 
(between the rocker sections) and outboard to form a duct for the defroster 
hose.  My beautiful 64 Spyder sat nose down on my sloping driveway for years 
when it was my daily driver.  After almost 20 years I decided to restore it 
and while doing so found the rot you speak of.  Defroster air was going 
directly into the wrong side of the rocker and being lost.  When I start 
something I will not listen to "can't be done".  I had to rip into a junk 
convertible to see what I was up against.  I cut away the outer rocker from 
top to bottom and for 14-18 inches to get at the remains of the ducting. 
Had to hand craft all of the bits and pieces and weld everything together. 
I promise you it is not for the faint of heart.  Not that I didn't look for 
an easy way out while I was in there but realized duplicating the factory 
setup was the only answer.  You have my sympathy but you need to find a 
metal craftsman to do the job.  One nice thing.  The defroster system puts 
out all the dry hot air anyone could ask for.
