'64 convertible questions

[Edward Trenn <imperial64@xxxxxxx>]

Hi folks! It's been a while, but I'm back with questions. And another Imperial.

I recently bought a '64 convertible that sat outdoors and needs a lot of work. 
(Window motors, bad chrome, worn top, rust... long list!) I've been through a 
lot of the mechanical issues in the past few years with my Coupe, but can 
anyone answer a few convertible-specific questions?

1. The top won't go down; motor sounds good but nothing happens. It appears 
that a cable on the driver's side is broken. Is there anything I can do myself 
to determine why the top won't work?

2. If I can't repair it myself, how much of the mechanism is "Imperial only?" 
Can the top motor, hoses and cables be located/replaced easily? How much does 
it cost to replace the worn top, should I go ahead and have all the mechanical 
work done at the same time? Chris Hawkins recommended a KEE top, but does 
anyone know where to purchase them?

3. How do I remove the rear seatback and/or fabric that holds the folded top? I 
want to get into the trunk, and the trunk lock is broken. I removed the bolts 
from the base of the rear seatback, but it still seems to be attached somewhere 
at the top. Any suggestions?

4. Is a remanufactured carrier bearing support available for the convertible? 
How about the idler arm? I know they are different on Imperial convertibles.

Thanks for your help,
Ed Trenn
